Washington State Department of Transportation bridge crews have determined that effective immediately, no commercial vehicles will be allowed to cross the State Route 165 Carbon River Bridge until further notice.
The restriction was prompted by the discovery Thursday afternoon that one of the four vertical legs supporting the bridge’s approach span has loosened from its concrete footing. WSDOT bridge crews are en route to the bridge to examine the support and determine what repairs will be necessary before the restriction can be lifted.
WSDOT crews will staff each end of the one-lane bridge Thursday night to ensure that only passenger vehicles cross the bridge. About 40 residents live between the bridge and the boundary of Mount Rainier National Park.
The single-lane bridge is located at milepost 11.5, three miles south of Carbonado in Pierce County. Aside from privately-owned logging roads, no detour is available for commercial vehicles.
