MoDOT to close Interstate 70 lanes overnight at the I-70/I-64/U.S&peri…

ST. CHARLES COUNTY - Crews with the Improve I-70 Warrenton to Wentzville Project will close all eastbound and westbound lanes of Interstate 70 at the I-70/I-64/U.S. 61 interchange overnight Feb. 11-12. Crews will be setting bridge girders that require large cranes and swinging materials over the interstate. All work is weather permitting.

All westbound lanes of I-70 will be closed overnight from 9 p.m. to 5 a.m. Wednesday, Feb. 11. Detours will be in place for westbound I-70 and southbound U.S. Route 61:

• Westbound I-70 will be reduced to one lane and detour to northbound Route 61, (exit number 210B), turn around at Pittman Avenue, and use the westbound I-70 ramp to access westbound I-70.
• Westbound I-70 traffic exiting to eastbound I-64 will detour exiting to northbound Route 61, (exit number 210B), turn around at Pitman Avenue, and use the eastbound I-64 ramp from Luetkenhaus Boulevard.

All eastbound I-70 lanes will be closed overnight from 9 p.m. to 5 a.m. Thursday, Feb. 12. 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).

Work may extend with an additional overnight closure Fri., Feb. 13 to finish any necessary tasks associated with setting the bridge girders.

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.
