GP2014-11 Environmental Review of a Grading Permit to Replace George E. Tryon Bridge

The Federal Highway Administration is proposing to replace the George E. Tryon Bridge location on County Road 427, also known as South Fork Smith River Road. The George E. Tryon Bridge is located approximately 2.0 miles east of Hiouchi. The project consists of the replacement of a two lane bridge, approximately 0.27 miles of road reconstruction, drainage improvements and grading. The existing bridge is a multi-span steel structure with a main span steel arch, built in 1948. It is structurally deficient, has fracture critical members, and has unknown foundation types, creating the potential for a negative impact or failure of the bridge during a seismic event. The primary objective of the proposed project is to replace the structure to improve public safety, maintain functionally of the road, and further protect the Smith River ecosystem.
