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 obsolete
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.
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.
