I know I already mentioned this website in previous posts, but I felt this website was cool enough to deserve a post of its own. The coolest bridge website is BridgeHunter.com.
This website is simply amazing. James Baughn has created a website featuring historic bridges across the nation. Anyone can submit photos or comments about the bridges. The navigation is brilliant. You simply click on a state, then a county. Then you are presented with a list of bridges in that county, with a thumbnail image if available.You will just have to check it out and see for yourself. I could spend hours just looking at all the cool truss bridges.
