Ponderosa Way Bridge Replacement

Project Description

The Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD), in cooperation with the U.S. Bureau of Reclamation (Reclamation), is proposing the replacement of the Ponderosa Way Bridge over the North Fork of the American River and minor roadway rehabilitation of 2.4 miles of Ponderosa Way. The project is in Placer County, California, located about 2.5 miles east of the town of Applegate and about 12 miles northeast of Auburn, on Reclamation-owned and maintained lands. A portion of the roadway to be improved also traverses lands owned by the U.S. Bureau of Land Management. Recreational use of the area is provided through a partner agreement with the California Department of Parks and Recreation (as part of the Auburn State Recreation Area). The bridge was constructed in the 1930s primarily for fire control access.
The proposed project will address the structural deficiencies of the Ponderosa Way Bridge and rehabilitate roadway and drainage issues on Ponderosa Way leading to the river and bridge. There are structural issues with the Ponderosa Way Bridge that have worsened over time, despite intermittent repairs to extend its service life. Undermining of the substructure continues and the bridge can no longer reliably accommodate larger vehicle loads. Reclamation has closed the bridge to vehicular traffic until corrective action can be taken. 
FHWA-CFLHD proposes the replacement of the existing structurally deficient bridge with a new bridge for a safer and more reliable river crossing. The new single-lane bridge will be designed for improved scour resistance and to meet current design loading standards and turning movement requirements for essential vehicles such as fire trucks. Along the approximately 2.4 miles of Ponderosa Way accessing the bridge on the north side of the river, FHWA-CFLHD will also perform gravel resurfacing and improve noted drainage issues through regrading and culvert cleanout or replacement, where necessary.
