The rehabilitation project on the north and southbound Interstate 229 bridges at Sixth and Atchison Streets in Saint Joseph will move to its next phase at the end of this month.
On Friday, Comanche Construction, Inc., working with the Missouri Department of Transportation, will open the southbound bridge and close the northbound bridge to all traffic.
During the final phase of the project, crews will make joint repairs to the northbound bridge.
Crews originally scheduled the southbound bridge to open in mid-August, but the bridge needed additional work.
MoDOT anticipates completing and reopening the northbound bridge in December.
Motorists will need to seek an alternative route during the closure.
All work is weather-dependent, and schedules are subject to change.
