ST. LOUIS COUNTY, Mo. – The planned expansion of Interstate 70 across Missouri will be the focus of several MoDOT open houses starting Monday in Wentzville. Governor Mike Parson signed the state budget two weeks ago, earmarking funding for the major project.

MoDOT said that Monday’s open house is really the kickoff for the statewide I-70 improvement program. Missouri’s budget for the 2024 fiscal year provides $2.8 billion in general revenue funds to add a third lane to I-70 in each direction from Wentzville to Blue Springs.

We’re told the project will plan, design, construct, and rehabilitate approximately 200 miles of I-70.

MoDOT is currently in the planning stage of this major effort. There will be no formal presentations at the open house. However, MoDOT engineers will be on hand to share preliminary information about the goals and construction schedules for the project.

MoDOT hopes to begin construction next summer. The goal is to be finished by 2030. Monday’s open house is taking place from 4:00 p.m. to 6:00 p.m. at the Wentzville Board of Aldermen meeting room. That’s at 1001 Schroeder Creek Boulevard in Wentzville.

On Tuesday, there will be another open house in Warrenton. That will again be from 4:00 p.m. to 6:00 p.m. at the Warren County Administration building on Mockingbird Lane in Warrenton.

There will also be five more open houses in other parts of Missouri.

If you can’t attend one of the open houses, online comments will be open through September 22.
