JEFFERSON CITY, Mo – Cole County Route AA, south of Russellville, is set to close next week at South Moreau Creek. While the driving surface of the bridge is replaced, a signed detour will route all traffic around the closure.
On June 8, construction crews, working with the Missouri Department of Transportation, will close the Route AA bridge over South Moreau Creek to all traffic to replace the bridge deck. The bridge is tentatively scheduled to reopen in late August. During construction, motorists will be directed around the closure via Cole and Moniteau County Route A, Moniteau County Route V, and Cole County Route C.
Built in 1965, the bridge's supporting structures are in good condition. The driving surface, however, has deteriorated, is in poor condition, and needs to be replaced. In addition to a new bridge deck, which will be the same width as the existing structure, crews will install new concrete barriers and place new guardrails at the bridge ends.
All work is weather-permitting, and schedules are subject to change.
As part of their January 2026 meeting, the Missouri Highways and Transportation Commission awarded a $755,964.75 contract for this work to E & C Bridge, LLC.
