Improve I-70
I-70 is a vital transportation corridor in Missouri, connecting the state’s two largest cities and carrying more rural daily traffic than any other route in the state. The 250 miles of I-70 through Missouri have been an engine for economic growth and prosperity.Missouri marks the distinction of being the birthplace to the interstate with the first interstate project under construction on I-70 in St Charles County between Fifth Street and Route 94/First Capitol Drive. This project broke ground on Aug. 13, 1956. However, being the first also makes it the oldest.
