Bridges to Prosperity Christmas Appeal


Christmas may have been and gone, but I thought it was worth a mention for Bridges to Prosperity's Christmas appeal, as there's still time to donate.

As hopefully most of my readers will know, the charity builds pedestrian bridges in some of the world's poorest and most remote rural communities, enabling people to reach schools, markets, health care and many other facilities.

Here are a few key statistics taken from B2P's UK Charitable Trust appeal email:

  • The World Bank estimates that there are more than 1 billion people globally (that's about 1 in 7) who lack year-round safe access to fundamental basic needs;
  • Bridges to Prosperity can construct a footbridge in just around three months;
  • Local government investment averages 50% for each project, meaning that B2P works closely to empower local communities with every bridge build;
  • Communities receiving a footbridge show a 12% increase in school attendance, a 24% increase in healthcare treatment, a 15% increase in local business, and an 18% increase in women in employment.

Here's what B2P UK Trustee Ian Firth has to say:
"The statistics are captivating, but what really motivates my work with B2P, more than any statistic, is the time I have spent in country with the communities served by our bridges.  Local residents, trained by our teams, have worked alongside us to construct their bridge, and are deeply invested in maintaining it. Mothers and fathers are no longer nervous to send their children to school or the market on their own, and farmers will plant a wider variety of crops because they don’t have to worry about being able to reach the market, no matter the season. Lives are saved because the health clinic or hospital is reachable year-round, and families are reunited across an otherwise-impassable river. It's this sort of transformative change that B2P is all about – safe access, for all.
"Last year, B2P built 37 footbridges serving 150,000 people in all. Next year, our goal is to build 42 footbridges, and to serve our 1 millionth person over B2P’s fifteen-year history. To do so, we have to raise £10,000, and we need your help."
If any of my readers would like to donate towards the appeal, you can do so online.

More information about the charity and its work can be found at their appeal website (it includes links to several other fundraisers which may be relevant to readers wishing to donate in US$ rather than £UK).

Après le déluge

It's been a busy year at Pontist Towers, so much so that my time available for blogging has been greatly reduced. That's unlikely to change in 2016, so you can expect posts here to remain fairly infrequent.

2015 ended with a great deal of bad news on the bridges front, with four bridges which I've visited and featured here either badly damaged or completely destroyed by flooding.


The bridges of the Cockermouth Keswich and Penrith Railway survived over 150 years before succumbing to the effects of Storm Desmond in early December. These bridges had been converted to a walking and cycling path after the railway was closed. Two of them were washed completely off their supports, the spans at White Moss (pictured above) and Brundholme (pictured below). When I visited them in 2013, they were rusty but reasonably robust relics, preserved and actively used, but it seems unlikely they will be restored any time soon. These photos are courtesy of Floodpics2015.


A number of other notable bridges were damaged or destroyed by the same storm. The Grade II Listed Pooley Bridge in Cumbria, dating from around 1764, was one of the most notable casualties, completely swept away by the sheer volume of floodwater (pictured, below, courtesy of Robert McEwen).


At the end of December, Storm Frank brought further devastation. It affected two bridges on the River Dee in Aberdeenshire which I visited in 2012.

The Grade B Listed Cambus O' May Bridge is a lovely suspension bridge built in 1905, and largely reconstructed in 1988. It has been badly damaged by floodwaters and may be beyond repair. Looking at footage of the flood, it's amazing it survived at all. To get an idea quite how much flood water passed down the Dee, compare the flood footage with the more normal level of the water in my blog post.

Another suspension footbridge on the same stretch of the River Dee has been less lucky. The Abergeldie Castle Footbridge, built in 1885 and also Listed Grade B, has been destroyed, except for its northernmost tower. This was already a derelict bridge, recognised on the Buildings at Risk register. It had been disused for a long time, and clearly will never be replaced. Footage in a Daily Mail report shows the wreckage, although quite understandably gives more prominence to the threat to Abergeldie Castle itself.


The same storm has led to severe damage to the New Invercauld Bridge (1859, Grade B Listed), cutting off Braemar from the rest of Royal Deeside; the collapse of Copley Bridge (1831, Grade II Listed, pictured above courtesy of Richard Kay); partial collapse of Wharfe Bridge in Tadcaster (18th century, Grade II Listed, first picture below courtesy of Rob Whiteley); and severe damage to Elland Bridge (18th century, Grade II Listed, second picture below courtesy of Richard Kay), and no doubt many others,



It has been reported that December 2015 has seen the greatest rainfall of any month in the UK since proper records began. With that in mind, it is difficult to blame these many bridge collapses on inadequate flood defences, or lack of maintenance. It seems initially more likely that they have experienced hydraulic loads and scouring action well beyond anything they had previously survived.

However, it seems clear that the recent rainfall and flooding are unlikely to be a one-off event, but that similar events could be experienced again far sooner than would normally have been expected. Historically, severe flooding has always been one of the greatest causes of the loss of bridges, and it's unreasonable to expect to be immune in the present day. It may be that no reasonable amount of flood defence or flood mitigation measures could have prevented these disasters.

I hope that at least some of the bridges affected by recent events may be restored rather than simply replaced, and that it spurs a wider effort to enhance the resilience of bridges throughout the UK. The examples here show they are important for heritage reasons and also as key transport links. Let's hope that the reins of economic austerity are loosened sufficiently to make a difference before the next time such severe flooding occurs.

Bridges news roundup

I've not rounded up any bridges news for a while, so here are a handful of things that caught my eye recently ...

Expert slams Garden Bridge business case
Apparently, the Garden Bridge project is a fiasco dressed up in a farrago, disguised as a farce.

The case for exempting projects from open procurement
Should pet projects like the Garden Bridge be permitted an exemption to normal competitive procurement, especially when it leads to things like the absurd procurement process by which Heatherwick Studio beat off two other designers to proceed with what had always been their own design proposal?

A Folly for London
Here's a lovely idea, a free, open, presumably not-pre-decided-at-all competition to come up with an idiotic idea whereby central London can be permanently ruined. Satirical, of course.

Boris agrees to underwrite Garden Bridge’s maintenance costs
Having previously promised that taxpayers will never have to cover the running costs of the Garden Bridge, London's mayor has had a change of heart. It's hard to see now why anyone else would cover those costs, when they know the London taxpayer is underwriting it all.

Design of new pedestrian bridge linking East Perth to Burswood revealed
Interesting new design in Perth, Australia. And look, it's got trees on it!

This Robot Can 3-D Print A Steel Bridge In Mid-Air
I expect that 3d printing of steel will never be an economic alternative to more conventional construction, but this is a genuinely exciting project, and I'd love to see more being made of robotics to help build complex structures.

Bridges news roundup

It's been a long time since I've done a bridges news roundup, so I'm going to keep most of these links short and sweet.

COBE, COWI and DISSING+WEITLING Wins Competition to Design 225 Metre Pedestrian Bridge for Køge
"Functioning as a solar screen on the south, pedestrian bridge opens to the city and provide panoramic views to the north."

Bouncy Squibb Park Bridge Closed For Being Too Bouncy
"It was designed to bounce (similarly to trail bridges in the woods) ... its movements had substantially increased, causing concern. It also started to tilt and sag in sections."

What a FAN-tastic design! Engineers create London footbridge that unfolds like a paper concertina
National newspaper in "gives credit to engineers" shock!

Footbridge Ribja brv / Arhitektura d.o.o
"Our aim was to design a bridge that has a construction as thin as possible, and bridge railing as transparent as possible."

Skyttelbron Bridge / Metro Arkitekter (Sweco Architects)
"The first idea, and perhaps the strongest in terms of design is that we wanted to bring color in an environment where virtually every­thing is in shades of gray, brown or green."

Bridge Over the Rhone / Meier + Associés Architectes
"This unity of form 'strides' over irregularities in the terrain and interacts logically with the location by progressively increasing its span in line with the mathematical principle of harmonic curves."

Floating bridge by RO&AD crosses the moat of a Dutch fortress
"The new 80-metre-long bridge follows the original route boats would have taken between a jetty on the edge of the moat and a raised entrance situated in one of the fortress's walls."

Must have a head for heights! London's Tower Bridge unveils £1m glass walkway 140ft above River Thames... costing just £9 to visit
"The pedestrians milling about on the pavements look as if they have come to life from a Lowry painting and there is nothing between them and my boots but a sheet of glass."

What Montreal’s All-New Champlain Bridge Should Look Like
"A peer of Taillibert, fellow architect Pierre Briset, is not confident in Taillibert's proposal. Briset believes Taillibert's plan is just a ripoff of the Millau Viaduct in southern France."

Calgarians celebrate bridge opening
"At a cost of $25 million, the span took five years to complete, one year longer than anticipated after the first bridge deck was destroyed in the 2013 flood."

Designer of Verrazano-Narrows Bridge: Low-profile genius preferred anonymity
"The greatest monuments to pioneering structural engineer Othmar H. Ammann are the ever-spectacular bridges born of his brilliance."

Léon Blum Viaduct Bridge / RFR
"We have chosen to create a structural continuity between the bridge deck and its vertical supports which are articulated at their base. In doing so, the area of the bridge which is most directly in contact with the town is freed from the kind of massive support commonly associated with this type of Bridge."

Bridges news roundup

I'm preparing some posts on groups of bridges I visited earlier this year in Yorkshire and in Lancashire, as well as on the Foryd Harbour Bridge. Meanwhile ...

Footbridge 2014
The Happy Pontist will be attending this conference from July 16-18 in London. The final programme has been released, and looks really interesting, so I'm looking forward to it.

Tees Transporter Bridge
A new book is being published on this bridge, and you can read a short sample online. I visited the bridge last year.

Taminabruecke
Very thorough website telling you more than you could possibly want to know about what will apparently be Europe's longest arch bridge, currently under construction.

New St Elmo Breakwater Footbridge
Of various bridges showcased on architectural websites recently, this one stood out for me as one of the most interesting.

London's Garden Bridge: "It feels like we're trying to pull off a crime"
It feels like that because you are trying to pull off a crime. Please hand yourself into the authorities immediately! The planning application is available online, and reveals the bridge to be a steel truss wrapped in ultra-expensive bronzed steel, rather than the pair of concrete flower-pots that I had expected. Please place some cushions on the floor around your chair before you read it.

Bridges news roundup

Here are a few news links that you have probably already seen. I'm travelling over the Christmas period, so it will probably be January when I finish off my reports on the IABSE study tour of north-east England.

New Thames footbridge gets planning
I really dislike this so-called Golden Jubilee bridge, which is proposed to cross the Thames between Battersea and Chelsea Harbour in London. The proposed span arrangement, with a short middle span flanked by two larger spans, with correspondingly larger support arches, just seems to have a really awkward rhythm to it. Although the bridge has now won planning consent, it still appears to have no funding. Incidentally, if you don't have a BDonline subscription, you can read their news stories by simply copying-and-pasting their headline into Google, then following the link from there: this bypasses the subscription protection.

£60m boost for Thomas Heatherwick's garden bridge
The Golden Jubilee Bridge is a ridiculous enough proposal, but the Garden Bridge is an absolute disgrace, an absolute eyesore where money is no object if it serves to boost the vanity of all involved. The total project budget is £150m, which is absurd for a bridge which is so utterly unnecessary.

Striking but useless… just like Boris
It seems I am not alone in this opinion. "It has just the right combination of whimsicality and instant-wow theme-park tackiness to make it a likely Boris project."

Shortlist announced for Hisingsbron in Gothenburg
So far as I can tell using Google Translate, five proposals out of 24 submissions have been shortlisted in this competition to design a new moveable bridge. The finalists are Snøhetta / WSP, Zaha Hadid, Tyréns / Beam / Schlaich Bergermann, Dissing + Weitling / Lenonhardt Andrä, and Wilkinson Eyre / Ramboll. That's a mighty impressive roll call of bridge architecture names, along with one or two less so. All five shortlisted entries are available online, where you can play guess-the-architect. All I can say is that three out of the five submissions are quite horrible, and you really have to wonder what the participants were thinking.

Beautiful bridge planned for China's Hunan province evokes knots, Möbius strips
This depressingly awful bridge proposal has been all over the architecture blogs, but few have managed such an inappropriate title. Beautiful? In the eye of the beholder, perhaps. If they are blind.

I told you so, St. Patrick’s Island Bridge
Following flood damage during construction earlier this year, parts of the RFR / Halsall designed footbridge had to be disassembled, setting back the date for the bridge's opening. Tallbridgeguy takes the opportunity to say "I told you so".

Bridges news roundup

Ok, I've finished my series of posts on the bridges of Rotterdam.

I'll move on next to various bridges in north east England, the focus of a recent weekend bridges tour, but before I do, here are a few news items that caught my eye ...

Pedestrian Bridge / Miró Rivera Architects
I've probably posted a link to this bridge design before, but it's so great I won't get tired of it any time soon (see picture, right).

Olympic Stadium Amsterdam / René van Zuuk Architects
I think I don't like this bridge, but I'm really not sure.

Flint and Neill and Moxon are brought in to provide some much-needed common sense.

A bridge too far: Dozens of tourists plummet into lake after ignoring 'maximum capacity of 40' warning sign
Brand new footbridge in China unable to carry crowd loading. No serious injuries but plenty of photos of the collapse. The photos appear to show that the upper chord of the bridge truss initially behaved as a catenary, with the floor and lower chord peeling away from the truss web members, suggesting completely inadequate truss connections as the main cause of failure.

Foryd Harbour Bridge opens to public
Here's a nice aerial video of this bridge being opened to the public. According to the contractor's website, it cost £6.5m, which is a greater than 50% increase over the £4m budget stated when the design competition was held. Back in 2009, I said the bridge design was "like to prove a challenge technically, financially, and in achieving the desired programme", and I correctly predicted it would over-run on both budget and programme. I also thought it might prove unreliable in service due to the very unusual opening mechanism. I guess we'll have to wait and see whether that also proves to be true - it may not, as the "drawbridge" mechanism in the contest-winning design appears to have been replaced in the final structure with a more conventional hydraulic ram.

I'm preparing posts on a handful of bridges I recently visited in London and Birmingham. Until those are ready, have some news:

Slickly futuristic. Super-slender piers. Structurally irrelevant arch features, sorry "armatures". Good? Bad? Who knows. Many more photos here.

Høse Bridge / Rintala Eggertsson Architects
A very "industrial" looking bridge in a natural landscape. I'm unconvinced by the desire to enclose the bridge in a setting like this, but it's unfair to judge only by photos.

Craigieburn Bypass / Tonkin Zulaikha Greer + Taylor Cullity Lethlean
A very different setting, another enclosed bridge.

Amazing camouflaged bridge
Go on, you must be able to think of a few more bridges out there that could do with being turned "invisible".

Bridges news roundup

Time for a few quick links to bridge-related news from elsewhere. I've been out visiting some bridges myself, so hopefully will start blogging those over the next few weeks.

Narrow Water bridge plan is put on hold
Considering all the fuss around the cancellation of the River Wear crossing, you may be forgiven if you're unaware of yet another "iconic" bridge scheme which has hit the skids for very similar reasons. This is a project for a new bridge between the Republic of Ireland and Northern Ireland, and in an odd parallel to River Wear, it is also a cable-stayed bridge with no back-stays, although nowhere near as adventurous as in Sunderland. The scheme had a reported €17.4m budget, but tenders have come in the range €26m to €40m, indicating a staggering failure to anticipate the realities of building this type of bridge (the disparity between tender prices is also quite remarkable). The most obvious comparison is Calatrava's Puente del Alamillo, which experienced such significant cost escalation that only one of two planned spans was built. What with this and Sunderland, the cost estimating profession should be hanging their heads in shame.

Parkland bridge to be designed without controversial arch
Funny news from Dallas - a hospital link bridge is to be redesigned without its supporting arch, because it's US$5m cheaper. So what on earth was the arch doing in the first place? This idea that major structural elements are only merited as decoration is quite absurd, but sadly not atypical of the American approach to bridge design.

Linking up London: sensational new bridges will create new communities and riverside homes
You can always rely on Homes and Property for the best summaries of bridge news. Surprisingly informative.

Scale Lane Bridge, Hull – review

A bridge with a twist, simple and sculptural.

£6.6m footbridge swings into action
It has been a long time coming, but Hull's "iconic" swing bridge opened to the public in mid-June, with a formal opening ceremony on June 27th. It has already been dubbed a "bridge to nowhere" by one critic. Elsewhere, reasons reported for the lengthy delay in its completion include having to raise the bridge by a mere 6 inches; the bridge's "tracking system" being too small; and concern over vandalism of the windows in the (currently empty) retail unit that sits on the bridge's pivot. One press officer grumbles "personally, I hate the word iconic".

Bay Bridge troubles began with design
Lengthy story of woe blames acceptance of inappropriate bolt specification for failure of Bay Bridge bolts.

Analysis: River Torrens footbridge in Adelaide cost higher compared with Helix footbridge in Singapore
Explain please. The Torrens bridge is not architecturally spectacular, nor does it seem to be structurally anything special (indeed it looks quite dull in most the images I've seen). So how can it possibly cost more than the structurally highly complex Singapore Helix bridge? Is it all down to its "waterfall feature"?

Contemporary Bridge: Berlin
This is an "ideas" competition for a 90m long "iconic" or "landmark" footbridge in Berlin. There are financial prizes, and some glory to be garnered, but essentially it's just a bit of fluff to keep workless architects occupied for a week or two, nobody has any plans to build any such bridge.

Palo Alto to consider design contest for 101 bike bridge
An invited competition is planned to "vet many designs simultaneously in the least amount of time and funding".

"Bouncy" footbridge set for strengthening
I visited this bridge at Pitlochry last year, and confirmed that it is indeed prone to bounciness, with a resonant frequency of about 1.7-1.8 Hz. For its 100th anniversary, it has been announced that it will receive "some upgrading and strengthening works to accommodate modern loading standards". Hopefully that's not really true - it has survived a century and it's hard to see that modern loads are anything worse than what it has already withstood.

Pedestrian bridge design unveiled
Designs for a new bridge at Penrith near Sydney, Australia show a garish yellow truss that looks like a jib which has fallen off a tower crane. More images at the Penrith Star.

Controversy over bridge which spans M8 in Glasgow
I have to say, nothing is more tedious than a futile debate about whether a bridge's disability-compliance is satisfied by whether its slope is exactly 1:20 or less. I remember having to meet that requirement on a bridge design once, for a bridge where the ground at either end sloped by more.

Bridges news roundup

So, what has being going on in the world of bridges news since I last did a round up? Well, let's kick off with four bridges that have appeared on the ArchDaily website ...

The Gold Line Bridge / Rivka Night + Andrew Leicester
Weird concrete bridge created with artist involvement. I can't say I really like it.

Ueberflieger Bridge / Agirbas and Wienstroer
Nope. I don't like this one either. Next!

Phyllis J. Tilley Memorial Bridge / Rosales + Partners Architects
Oh, now this is more like it. A really elegant little arch-supported stress ribbon bridge, in Texas. I wonder who the engineer is? Let's read the article. Er. Um. No engineer, apparently (par for the course for ArchDaily). I know, let's look up the datasheet on the architect's website, I'm sure they will credit their collaborator. Umm, no. Hey, maybe there was no engineer! Wait, here's an article about the bridge by the American Society of Civil Engineers, this will tell me! Hmm. Architect says this, architect did this, architect did that. Yadda yadda. Oh wait, here it is right at the end: Schlaich Bergermann and Partners, with Freese and Nichols. Really now, did that have to be so difficult?

Hovenring, Circular Cycle Bridge / ipv Delft
At this point, I feel tempted never to link to the ignoramuses at ArchDaily ever again. But here's one more, for now.

Snow-free pedestrian bridge by Erik Andersson Architects
Et tu, Designboom? A simple, elegant bridge, designed apparently without the aid of an engineer.

Mystery of Yuma's swastika bridge explored
So, why does this concrete bridge in Arizona have forty swastikas adorning its sides?

Chinese fireworks truck explosion destroys bridge
Self-evident from the title.

Sicily bridge project sinks in Italy budget mire
No surprise at all to see world's longest suspension bridge an early casualty of Italy's political instability.

$320,000 a year to maintain new River Torrens footbridge to Adelaide Oval
They're kidding, surely. For what and where it is, this AUS$40m footbridge seems amazingly expensive, as do the reported maintenance costs.

Council approves LRT bridge design
The council in question being Edmonton, Canada, who have opted for an extradosed solution for their new light rail bridge. I especially liked the comment from one councillor that it would be more expensive than alternatives "'cos Wikipedia sez so" (I paraphrase). "At that point, Coun. Dave Loken pretended to repeatedly stab himself in the forehead with his microphone."

Engineers repairing famous Tarr Steps clapper bridge applaud 3,000-year-old design
Flood-damaged ancient bridge to be put back together for £10,000. No sightings of Humpty Dumpty.

Scotland to be cut free as closure of bridge that connects the UK announced
Great headline, thanks to Tallbridgeguy for spotting this story, although it's worth noting that the body of the story doesn't confirm that closure is proposed (for the Union Chain Bridge, Britain's oldest suspension bridge), just that there's no money for refurbishment. The comments at the article's end are particularly splendid.

This Beautiful Wooden Pedestrian Bridge Was Crowdfunded When The City Couldn’t Pay
Rotterdam footbridge paid for piece-by-piece. Perhaps someone should tell those looking after the Union Chain Bridge? It wouldn't be the first use of crowdfunding for a bridge in the UK, after all.

Binladen bridge could spark war
Proposed bridge between Egypt and Saudi Arabia criticised as tantamount to an act of war against Israel. While the article is largely nonsense, the serious point that bridges have often historically been built to facilitate military strategy is worth noting.

Egypt-Saudi bridge: Is the government sacrificing natural resources for short-term gains?
You could read this article and not even realise it's the same bridge, so different is the perspective. Here, concerns are reported over the lack of transparency regarding its environmental impact.

Campaign planned against Braemar footbridge
I featured this proposed bridge a couple of months ago. According to the BBC, it may not be supported by all locals. A blog post here gives the arguments against development in the Braemar area.

Bridges on the Aston-Sheffield-Leeds motorway
Excellent post at the Tallbridgeguy blog highlighting some innovative and very interesting concrete bridges on the M1 motorway. It's well worth following the link to Concrete Quarterly for photos of several more related bridges, as well as a link to an interview with Ron Brindle in a follow-up post. Great stuff.

Bridges news roundup

I have a few more bridge reports to post, just waiting to get some time to sort out the photographs. While that waits, here are some bridges in the news ...

The 1,000-year-old wooden bridges that keep modern China moving
I'm no fan of the Daily Mail, but it's great to see these brilliant bridges getting some attention. On this subject, see also my review of Chinese Bridges.

Tarr Steps to be rebuilt following flood chaos
One of Britain's oldest bridges destroyed in flooding late last year.

Whitchurch Bridge denied £700,000 tax rebate
It would be interesting to see if freedom from taxation in perpetuity could be used to help incentivise new privately-funded bridge construction today ...

New Exeter footbridge is a British first
I saw this reported elsewhere as Britain's first FRP footbridge, which of course it isn't, but it is remarkable to see a Grade II Listed structure replaced entirely in plastic and still retain its heritage status.

Multi-coloured footbridge is made from 400 giant pieces of Meccano costing £90,000
Huh?

Econtainer Bridge Competition Winning Proposal
Competition winner in Israel proposes to build parkland bridge out of old shipping containers.

New Brayford level crossing footbridge designs submitted
It's great to see evidence that Network Rail are becoming more open to including aesthetics in their bridge designs, at least where public or political pressure demands it. The latest designs (top) are a vast improvement on the previous ones (bottom).



$40 million Adelaide Oval footbridge over the Torrens will be ready for the Ashes, State Government says
Or heads will roll, presumably. This wasn't the most interesting of the designs submitted for this bridge, but I don't think they have all been made public, unfortunately.

Coalition deal agreed on River Don crossing in Aberdeen
Nice picture, the ghost of Robert Maillart seems alive and well and living in Abereen.

Limmat Footbridge and Promenade Lift
Presumably lifts never break down in Switzerland?

Dallas council approves funding for second Calatrava Bridge
Amid concerns over cost over-runs and maintenance costs. I can't help thinking all these cities buying in designer-brand bridges are backing yesterday's horse.

Calatrava "Bridge" No. 2: We're Spending an Extra $7 mil to put Lipstick on a Pig
I'm only linking this story because the headline is so amusing.

Calgary’s Peace Bridge rated among world’s top designs of 2012
Calatrava bridge in positive news story.

Smart Design and Super Materials Are Stretching Bridges
Bridge design and construction technology isn't stuck in a rut - a brief guide for outsiders.

Design tweaks to keep Blue Bridge within budget, says city hall
Translation: Victoria, Canada's new bascule bridge design is over-running on cost, but luckily we've spotted it early. It's also known as "value engineering". Full detail of the "tweaks" are here, it's a shame in particular that the bridge truss cross-sections are to be compromised. I wonder what the architects think?

Bridges news roundup

Time for a quick last post before Christmas ... hopefully I will get some time over the festive break to deal with a backlog of bridge visits, five from around the UK, one from Greece, and get those posted up here in the New Year. Meanwhile, here is the news:

Pedestrian Bridge / HHD_FUN Architects
Chinese footbridge. I am not sure whether all the arched steelwork on top is actually doing anything structural, or is merely decorative.

Compiegne Bridge / Explorations Architecture
An excellent highway bridge design, the Vierendeel arches are exquisite.

Transforming the Bridge Competition Winners
A variety of proposals to transform the abandoned Detroit Superior Bridge.

Melkwegbrug / NEXT Architects
I think I've mentioned this before. But here it is again. Lovely photos.

Pont de Singe Installation / Olivier Grossetête
Thoroughly delightful artwork / bridge supported by balloons. Sadly, here's how it really looked when the Pontist paid it a visit in September (click the photo to see it full size).

River Lee pedestrian crossing plans unveiled
Bridge will lift a mere 4m. Huh?

£600k bowstring design for new footbridge in Boston is backed by council
See previous Pontist report.

Bridge full of life
Contemporary Chinese bridge-cum-classroom with more than a few echoes of classic Chinese covered bridges.

China to Complete World’s First All-Glass Suspension Bridge in 2013
Anywhere other than China, I would dismiss this story out of hand.

Festina Lente / Adnan Alagić, Bojan Kanlić & Amila Hrustić
Cute.

Footbridge Over the Railways / DVVD | Architectes – Designers
An interesting approach to the inherent difficulties of keeping railway authorities happy.

That's all for this year, have a Happy Christmas!

Historic span receives £630k makeover.

AZC: Bridge in Paris
This bridge was made for wobbling. Erm, I mean bouncing. Don't worry about the practicality, this is an entertaining bit of fluff.
