The Missouri Department of Transportation (MoDOT) is seeking public input regarding northbound Interstate 29 Bridge Replacement and Rehabilitation over U.S. Route 169 in Clay County.
The comment period opened is open now through Monday, Oct. 13 at 4 p.m.
The public is invited to leave questions and comments at www.modot.org/projects/northbound-interstate-29-bridge-replacement-and-rehabilitation-over-us-route-169-clay.
The I-29 bridge replacement/rehabilitation project in Clay County will include the replacement of the northbound I-29 bridge over NB U.S. 169 and the rehabilitation of the NB I-29 bridge over SB U.S. 169. Construction is scheduled to begin in January.
Details
The I-29 bridge replacement/rehabilitation project in Clay County will include the replacement of the northbound I-29 bridge over NB U.S. 169 and the rehabilitation of the NB I-29 bridge over SB U.S. 169.
This project was originally going to be staged construction with both bridges set to undergo a rehabilitation. On further inspection, it was determined that the northbound I-29 bridge over northbound U.S. 169 was nearing the end of its service life and needed to be replaced. The project now requires a full closure for the replacement and rehabilitation.
Traffic Impacts
The northbound I-29 bridge will be closed for around three months in late winter/early spring and will open to traffic by June 1, 2026, in time for World Cup traffic.
Northbound U.S. 169 will be closed for a weekend while the northbound I-29 bridge is demolished.
Both bridges will be open with no traffic impacts before World Cup events begin in June 2026, MoDOT says on its website.
Detour
Northbound I-29 will be closed, and traffic will be detoured onto northbound US 169 to westbound Hwy. 152.
The U.S. 69 to northbound I-29 ramps will be closed for the detour.
There is potential for various lane closures on southbound U.S. 169 throughout the bridge rehabilitation.
