The Oakville Cross Road Bridge Replacement Project is
located in the central portion of unincorporated Napa County slightly northeast
of State Route 29 where Oakville Cross Road passes over the Napa River. The
purpose of this project is to replace a structurally deficient and functionally
The proposed project replaces the existing bridge with
a new structure. The new bridge will be a 2-span, cast in place conventionally
reinforced concrete box-girder bridge structure requiring the construction of
two abutments with retaining walls and one pier. The new structure will carry
two lanes of traffic. The bridge will pass over the Napa River at a higher
elevation to meet current hydraulic design standards. Once the bridge portion
of the project is complete the channel will accommodate fish passage during low
flows and to allow loose rock slope protection on both channel slopes to
protect the bridge abutments from scour and erosion.
The project will include onsite and offsite Riparian
Restoration. Other items of work include tree trimming and tree removal,
modification to existing culverts and driveways and traffic safety features
such as bridge rails and guardrails.
