Please follow all detour and construction signs while the bridge is being repaired.

The bridge was originally constructed in 1931 and is a two lane, 310 foot long concrete bridge built into the side of a hill along a ravine. It was retrofitted in 1996 to address several deficiencies; however, repairs are needed again in order to extend the life of the bridge.

Concrete on the bridge is cracking and breaking apart, exposing reinforcing steel. The bridge railing is in poor condition and presents a hazard for vehicles due to the steep slopes. There are signs of soil sloughing around the foundation of the bridge. One footing has been exposed. Due to these conditions, repair work became necessary.
