Construction work to place new bridge deck on Thompson River Bridge begins March 2, 2020

Bridge Work

Drivers headed west out of Chillicothe on Route 190 may encounter construction delays beginning Monday, March 2.

A rehabilitation project to place a new bridge deck on the Thompson River Bridge will be led by contractors from Comanche Construction Inc., working with the Missouri Department of Transportation. This bridge is included in Gov. Parson’s “Focus on Bridges” program passed by the Missouri General Assembly during its 2019 session. The program appropriated $50 million in state general revenue to fund 45 high priority bridge projects throughout the state.

The first week of work will be at a driveway entrance on the northwest corner of the bridge. Bridge construction will begin March 9, 2020, and will be staged to allow one lane of traffic over the bridge throughout much of the project, with a 10-foot width restriction. Temporary traffic signals will be used to guide motorists through the work zone.

During two portions of the project to connect the new bridge deck with the roadway, complete closure of Route 190 at the bridge will be necessary. The exact dates of the closures are not known at this time, but one is anticipated in mid to late June and one in mid to late October. During those closures, traffic will be directed over a signed detour route on Routes 190, 6 and U.S. Route 65.

Contractors plan to have the bridge open to two-way traffic by Thanksgiving. As with all construction, work is weather-permitting, and schedules are subject to change.
