Bridge 11 (Whipple), Bridge 12 (Knapps), and Bridge 63 (Carson) Strengthening Project

This project will strengthen and rehabilitate three Clark County bridges: bridge No. 11 carrying Northwest 179th Street over Whipple Creek north of Salmon Creek, bridge No. 12 carrying Northwest Krieger Road over Whipple Creek near Green Lake, and bridge No. 63 carrying Northeast 67th Avenue over Mill Creek south of Battle Ground. Bridge supports will be rehabilitated on the bridges, removing the existing load weight restrictions.
