Aging Infrastructure

Our roads, bridges and transit systems are too old and need repair or replacement.

What Lies Beneath?
Why must we invest in rebuilding highways from the ground up? A new video, Life Cycle of a Highway, produced by the Missouri Department of Transportation (MoDOT), vividly illustrates what happens below the surface of highways after 50 years of car and truck traffic have passed over them. Drivers can feel the bumps and potholes, but what they don't see is how rock and soil layers supporting the roadway crumble regardless of what is done to the surface. Eventually, the highway has to be completely rebuilt and the price tag grows the longer the work is delayed. MoDOT is making the video available to all states to use in communicating the need to reinvest in highways. Contact for more information.
