Grand Coulee Dam Bridge – Coulee Dam, WA
Highway Bridge Truck Impact Evaluation
On July 24, 2006, the bridge located along State Highway 155 in Coulee Dam, Washington, which crosses the Columbia River just north of the Grand Coulee Dam, was impacted by a truck. The impact took out some of the sway bracing of the multi-span steel framed bridge. We were retained by the insurance company representing the trucking company to determine the extent of damage and to provide repair recommendations for the bridge that was associated with the truck impact. We were also asked to review the scope of repair proposed by WSDOT.
