MGE prepared the Type Selection Report and completed the final design and PS&E for the replacement of two trail bridges located on the Caribou Trail near the PG&E Caribou Power House within the Plumas National Forest. Both trail bridges provide access over the North Fork of the Feather River. The existing bridges which consisted of single-span, timber deck cable structures, were replaced with single-span steel truss bridges with timber decking. Both bridges were prefabricated in two sections to facilitate transportation to the site via helicopter as a result of access limitations. A temporary support tower was utilized in the river to provide temporary support while the two bridge sections were spliced together to complete the installation.
Client: USDA Forest Service
- No vehicle access to the site
- Sikorsky Skycrane Helicopter used to place bridge sections
