Also, Senesfan (post 67) seems to be suggesting that Sydney Harbour bridge is the same colour as the Golden Gate Bridge, it isn't. Sydney Harbour bridge would have been a nice inclusion, or the Tyne bridge that it's a copy of, both very beautiful in their own way.
Excellent article. Also worth a mention: Chester's Eastgate Clock, positioned on a bridge across Eastgate Street, In Chester, Cheshire, UK. Apparently the second most photographed clock in the world.
