Rattlesnake Bridge

Transportation Revamp: Lemhi County gets a new bridge

This steel superstructure replaces a truss bridge in Lemhi County, Idaho. Consisting of ASTM A588 weathered steel plate girders with gravel ballast over steel decking, this 190-foot span, single lane, HL93 bridge provides access to property owners on the west side of Salmon River.

The bridge was completed and re-opened in January 2016.
