The Wildcat Creek Bridge project required a detour structure to accomplish the project.

US 12, Wildcat Creek Bridge

Location: White Pass

General contractor: Graham Contracting

The previous Bridge crossing Wildcat Creek on US 12 was built in 1936 and was structurally deficient. The bridge was deteriorating and needed to be replaced. This project detoured existing US 12 highway traffic across Wildcat Creek on a detour structure and replaced the previous bridge with a new structure. The Washington State Department of Transportation (WSDOT) required an accelerated schedule to minimize impacts to the traveling public and local community while protecting mature trees, vegetation, and the sensitive habitat of Wildcat Creek. Additional scopes of work included providing structure designs, plans and specifications for the project, embankment, excavation, grading, paving, signing, striping, retaining walls, restorations and erosion control. Graham was also responsible for coordinating the temporary and permanent relocation of existing utilities.
