St. Louis Work Zones Feb. 19-25…

ST. LOUIS - Drivers in St. Charles County who use I-70 overnight should consider alternate routes or allow extra time as 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).
