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.

Improve I-70 Public Involvement

In Fall 2023, the Missouri Department of Transportation invited the public to attend seven informational kick-off meetings along the I-70 corridor to learn about the proposed plan and next steps for I-70.

The most recent round of public information meetings was Wednesday, May 1, and Thursday, May 2, 2024, for first Improve I-70 project: Columbia to Kingdom City.
