This Is What The Nation's Crumbling Infrastructure Really Looks Like (PHOTOS)

Hundreds of thousands of bridges across the country are in bad shape, and the result can be tragic.

Artist and researcher Nickolay Lamm took photos of structurally deficient bridges in his hometown of Pittburgh to show what the problem really looks like. Severe rust, corrosion and structural defects may make you think twice about driving over structurally deficient bridges in your area (scroll down for a state-by-state map).
