JEFFERSON CITY, Mo. (AP) — Touted as one of the first interstate highways, a 200-mile span of Interstate 70 between suburban St. Louis and Kansas City stands as a prime example of the challenges facing the nation's roads.
Built in the 1950s and '60s with a 20-year-life expectancy, the four-lane highway is crumbling beneath its surface and clogged with traffic as it carries more than 30,000 vehicles a day on many of its rural stretches, requiring more frequent repaving. The cost to rebuild and widen it is estimated at $2 billion to $4 billion — as much as five times the projected yearly construction and maintenance budget of Missouri's transportation department.
