MoDOT to close Interstate 64 lanes between Route 364 and Route K for pavement repairs

ST. CHARLES COUNTY - Crews with the Improve I-70 Warrenton to Wentzville Project will close two eastbound and westbound Interstate 64 lanes between Route 364 and Route K for pavement repairs starting Monday, June 1. All work is weather permitting.

Two eastbound lanes will close nightly from 8 p.m. to 5:30 a.m. starting Monday, June 1. This closure is expected to last two weeks. One eastbound lane will be closed around the clock. This section of I-64 normally has three eastbound lanes.

Starting Monday, June 8, two westbound lanes will close nightly from 8:30 p.m. to 9 a.m. between Route K and Route 364.

This work is part of the widening of Interstate 64, adding a third lane in each direction between Route 364 and the I-64/I-70 interchange.

The Improve I-70 Warrenton to Wentzville Project covering the eastern portion of I-70 was awarded in November 2024. Construction is tentatively set to take place 2025-2028.

This work is part of the second project in MoDOT's Statewide Improve I-70 Program. Improve I-70: Warrenton to Wentzville is a $600 million Design-Build project that will improve the 20-mile stretch of I-70 between Warrenton and Wentzville. The project was awarded to the Improve 70 Alliance team in November 2024. Construction is anticipated to be complete by the end of 2028.

Missouri's FY2024 budget, approved through the state legislative process and signed into law by the governor, provides $2.8 billion in General Revenue to build a third lane of I-70 across the state. The program will plan, design, construct, reconstruct, rehabilitate, and add a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville.
