The Grand River Bridge on Carroll County Route M was built in 1983, and carries approximately 300 vehicles per day. The driving surface of the 1,620-foot long bridge needs a preventive maintenance treatment and the supporting structures are showing signs of age and require repair. MoDOT is designing a project to complete this necessary work.


Route M will close at the bridge during the project which will go out for contractor bids as part of MoDOT's May 2023 letting and could be awarded to a contractor at the January meeting of the Missouri Highways and Transportation Commission.

Planning and Design Phase

MoDOT's Planning and Design team are designing a project which will rehabilitate the bridge's driving surface and repair the super and substructures at the bridge.

MoDOT solicited the public's input during an open comment period, held Sept. 6 - 20, during the project's Design phase. The comment period is now closed.


Not Started
Contract Letting, Award & Notice to Proceed

This project is currently scheduled to go out for contractor bids as part of MoDOT's May 2023 letting, when contractors may submit competitive bids on the project. The Missouri Highways and Transportation Commission could award the project at their June 2023 meeting.


If the project is awarded in June, the Notice to Proceed date  - the earliest date on which the contractor could begin work - will be in August 2023, though construction may not begin at that time.

Not Started

When the contract is awarded, the contractor will work with MoDOT to determine the exact schedule of work.

At this time, the roadway is expected to close during construction. The exact date of the road closure and the planned reopening date will be established after the contract is awarded.
