ST. CHARLES COUNTY – Crews with the Improve I-70 Warrenton to Wentzville Project will close all eastbound lanes of Interstate 70 at the I-70/I-64/U.S. 61 interchange tonight for bridge work. All work is weather permitting.
All eastbound I-70 lanes will be closed overnight from 9 p.m. to 5 a.m. Wednesday, February 18. Detours will be in place for eastbound I-70 and southbound U.S. Route 61:
- Eastbound I-70 traffic will be reduced to one lane and detour to eastbound I-64 exit ramp (exit number 210A) and then detour using the eastbound I-70 left exit ramp to access eastbound I-70.
- Southbound Route 61 traffic will be reduced to one lane and detour to westbound I-70 and use the Route Z interchange (exit 209) to turn around to head eastbound on I-70 or eastbound on I-64.
- Eastbound I-70 traffic exiting to northbound Route 61 will take the eastbound I-64 exit ramp (exit 210A), detour to eastbound I-70 using the I-70 left exit ramp, turn around at the Route A interchange (exit number 211), and exit to northbound Route 61 (exit 210B).
- Westbound I-70 traffic exiting to eastbound I-64 will detour and use the Route Z interchange (exit 209) to turn around to head eastbound on I-70 and exit to eastbound I-64 (exit 210A).
This work is part of the Improve I-70 Warrenton to Wentzville Project covering the eastern portion of I-70. It was awarded in November 2024. Construction is tentatively set to take place 2025-2028.
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.
