Willapa Hills State Park Trail-Overpass
The proposed bridge will be an S-shaped, three-span weathering steel truss with a concrete deck, and a 10-foot-wide trail surface. An overlook area at the east end of the bridge has been incorporated into the design to provide views of the surrounding areas. The bridge approaches will be approximately 400 feet long to accommodate a 5% grade to meet ADA standards. Safety railing/fencing will be installed along the bridge and the tops of the approach walls to serve as fall protection. Natural stone will be used to face the abutment wing walls and along the edges of the overlook area, and embankments for the trail approaches will be landscaped with a combination of grasses and shrubs.
