Twickenham Bridge

Haven't blipped a bridge in a while. This is Twickenham road bridge, taken from a moving train on the next door railway bridge at some speed - so not too shabby for a Blackberry, I think.

Twickenham Bridge was built to provide unemployment relief during the Great Depression, and shares with Chiswick Bridge (part of the same works) the distinction of being examples of that rare breed, Thames Bridges for which you've never had to pay a toll to cross.
