Peter's Bridge, Norwich
I always prefer to visit a bridge before covering it here, but I have no plans to go anywhere near Norwich soon, and this bridge looked worth featuring.
It opened to the public last month, and spans the River Wensum in Norwich city centre. Spanning about 30m, it is 80m long in total, shaped like the letter "J" in plan. Designed by Ramboll, it is named for Peter Jarrold, who first came up with the idea for a bridge at this site twenty years ago.
The bridge's form is unusual - there are plenty of bridges with curved decks like this, but very few with so little obvious means of support. Most are suspended from arches, or masts, or less frequently held up by larger girders or trusses.
York Millennium Bridge has several similarities. The photos are unclear, but there appear to be a small number of very slender supports below the main edge girder.
as I've illustrated here before. However, it's also prone to vandalism and to the risk of rapid corrosion due to trapped water, particularly in the British climate.
Quibbles aside, the overall appearance is daring without unnecessary flamboyance, and it looks like a fine new structure, nicely detailed.
