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 October 13-14. Crews will be setting bridge girders that require large cranes and swinging materials over the interstate. All work is weather permitting.
All westbound I-70 lanes will be closed overnight from 9 p.m. to 5 a.m. Tuesday, October 14. Detours will be in place for westbound I-70:
- 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 lanes of I-70 will be closed overnight from 9 p.m. to 5 a.m. Wednesday, October 15. 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 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, detour to eastbound I-70 using the I-70 left exit ramp, turn around at the Route A interchange (exit number 212), and exit to northbound Route 61.
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.
