Project Timeline


MoDOT has contracted with Garver Inc., to design the new bridge decks for the Livingston County U.S. Route 65 Grand River Bridge and the Route 190 Thompson River Bridge.


Right of Way Acquistion

At this time, MoDOT does not expect to acquire permanent right of way for the projects. Temporary construction easements may be needed for roadway entrance realignment of the U.S. Route 65 access road to Chillicothe water treatment facility and conservation area to the north end of the bridge.

The projects will remove the Route 190 entrance onto County Road 229 to the east end of the bridge.

Roadway entrance modifications are necessary due to improving sight distance and safety of motorists.


Public Input

The public was invited to provide input about the design, proposed construction period, proposed detour route and any other concerns they may have via  this webpage.

A public meeting was held on Thursday, May 23, from 4 to 6 p.m. at the Chillicothe Municipal Utilities Building located at 920 Washington St., Chillicothe, MO.

Project Bidding and Award

The projects were let for contractor bidding in August 2019. The Missouri Transportation and Highways Commission awarded a $4,149,172.70 contract for the U.S. Route 65 bridge to Radmacher Brothers Excavating Co., Inc. and a $3,468,748.02 contract for the Route 190 bridge to Comanche Construction, Inc. during their September 2019 meeting.

Frequently Asked Questions


Q: Will MoDOT close the road during construction?

A: For the majority of the project, only one lane will be open for use traveling in both directions. Construction will be staged so that half of the bridge will be replaced at a time. Flaggers will direct motorist through the work zone. There will be a brief period of time in which the bridge will be closed in order the pour and cure the concrete driving surface. During this time period motorists will be directed by a signed detour around the closure.


Q: Is there a detour?

A: During the short period each road will be closed a signed detour will be in place directing traffic around the work zone.


Q: Will MoDOT need to acquire any right of way?

A: The only anticipated right of way purchases at this time are easements on city owned property.


Q: Who can I contact if I have further questions?

A: Questions about the project may be directed to MoDOT Customer Service at or by phone at 888 ASK MODOT (1-888-275-6636Image removed.Image removed.Image removed.).
