Bridge work will slow traffic on State Route 107 over the Chehalis River South of Montesano this Spring as contract crews from Roglins Inc will begin a bridge rehabilitation and painting project across the river from the boat launch.

Communications Specialist Tina Werner with the Washington State Department of Transportation tells us that after feedback from the community, WSDOT has changed parameters of the project to replace the timber on the south approach of the 58-year-old span while also installing modern safety rails and painting the steel portions of the structure.

I attended a Montesano meeting in 2016 where planners expected a full closure of the bridge and were considering a 40-minute detour around the bridge. Truck traffic will still have to take this route. Instead during construction, the bridge will remain open to local traffic who will encounter one-way alternating traffic controlled by a signal as well as occasional night and full weekend closures.


The South side of the bridge approach will look like the North side when the project is completed.

When the work is done, the timbers will be replaced and the South end of the bridge will look like the North end.
