The Kansas Department of Transportation will close westbound I-70 through downtown Topeka this weekend to complete pavement patching on the Polk-Quincy Viaduct.

Weather permitting, westbound I-70 will be closed from 8th Street to Topeka Boulevard beginning at 12:00 a.m. on Saturday, July 22. The closure will be in place until work is complete, or no later than 11:59 p.m. on Sunday, July 23.

The 8th Street exit will be the last open exit for westbound motorists. Through traffic will follow signed detours and be routed south to I-470, or north to K-4 to U.S. 24 to U.S. 75. Or drivers can use the local street detour: Madison Avenue to 6th Street to Topeka Boulevard to the 1st Street I-70 on-ramp.

Eastbound I-70 traffic will remain open, but still reduced to one lane.

Additional I-70 closures are expected in the coming months, as more pavement patching is needed on the viaduct. KDOT is working with the City of Topeka to schedule the closures and will provide information when available.

Both directions of I-70 will stay reduced to one lane until construction of the viaduct’s replacement is complete. The Polk-Quincy Viaduct project is scheduled to begin in early 2025.

KDOT urges all motorists to be alert and obey the warning signs when approaching and driving through a highway work zone. To stay aware of all road construction projects across Kansas, go to www.kandrive.gov or call 5-1-1.
