Two very nice sources have just come out showcasing a range of often spectacular bridges, mostly great although one or two merely bizarre.
Deputy Dog has big images of "nine amazingly unique bridges you may not have seen". Some are amazing and very attractive: the delightful Henderson Waves bridge in Singapore, for example. Arrayed on the opposite side are the strangely totalitarian Octavio Frias de Oliveira Bridge and the Juscelino Kubitschek Bridge, both in Brazil, triumphs of muscular spectacle but certainly not of elegance.
Also just out is the brochure for the Footbridge 2008 Awards. This has photos of all the winners and runners-up, plus extensive write-ups giving more background detail. There are few if any duds in here, with the Simone de Beauvoir Footbridge, Svratka River Bridge and the Sackler Crossing amongst the best of those featured. These are generally more sober structures than showcased at Deputy Dog, but they don't suffer for that.
