I have walked over, done a 10K race over, and its on one of my favourite 100mile cycle routes, the Humber Bridge, so I watched the Channel 5 program on it last night, and what an interesting program it was, the road platform is shaped like a plane wing so that when its windy the air pressure under the bridge is lower than above so the bridge becomes more stable.
Its on Channel 5 catch up if you want to watch, other bridges also have their own program.
