So I typed in my address and got this map, indicating the state of the bridges within 10 miles of my house.
I presume the green icons represent bridges that are in decent shape (a helpful graphic should have a complete legend); the red ones, obviously, are not. Although the green icons, thankfully, outnumber the red ones, there's still a distressing number on red ones. Doesn’t fill a guy with a lot of confidence … especially since the red icon right next to the “pin” on the map is a bridge I use several times a week.
Amuse and/or frighten yourself by visiting http://t4america.org/resources/bridges/.
