Skyway road westbound, over butte creek, 0.5 miles southeast of humbug road construction of a new 222 foot long multi-span prestressed cast-in-place

The Federal Highway Administration awarded $1.1M to the California Department of Transportation (Caltrans) on May 27, 2025, under the Highway Planning and Construction program (CFDA 20.205) to design and construct a new 222-foot, multi-span prestressed cast-in-place reinforced concrete box-girder bridge over Butte Creek on Skyway Road westbound, approximately 0.5 miles southeast of Humbug Road. The project includes construction of a bridge structure providing 42 feet of clear width and approximately 400 feet of approach roadway reconstruction on each side, along with removal of the existing bridge and implementation of a temporary detour to facilitate construction activities.

This Formula Grant award represents federal assistance to California's state transportation agency for highway infrastructure improvement and bridge replacement. As a formula-based allocation under the Federal-aid Highway Program, the funding supports the state's ongoing responsibility for planning, constructing, and improving transportation infrastructure. The project aligns with the Highway Planning and Construction program's mission to support comprehensive highway preservation and improvement activities across the nation.

Project description

Skyway road westbound, over butte creek, 0.5 miles southeast of humbug road construction of a new 222 foot long multi-span prestressed cast-in-place reinforced concrete box-girder highway bridge providing 42 feet of clear width with approximately 400 feet of approach roadway reconstruction on each side of the proposed bridge along with the removal of the existing bridge. A temporary detour beyond the approach roadway work will be required.
