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.
