Road Closure for Repairs on Black Lake-Belmore Road Bridge

CONTACT:    Brian Meier, Project Manager, (360) 867-2333 or

OLYMPIA – Thurston County Public Works announces a temporary closure of the Black Lake-Belmore Road Bridge for significant repairs, starting on June 17, 2024, and continuing until mid-October 2024. This closure is necessary to address potential safety concerns and maintenance issues with the roadway on both sides of the bridge.

During this period, crews will drive hundreds of timber piles and install a geogrid to stabilize the roadway. This work will significantly increase noise during construction hours scheduled Monday – Friday from 7 a.m. to 8 p.m.
