California State Route 113

California State Route 113

California State Route 113 is a north–south state highway in the northern Central Valley of California connecting the Sacramento metropolitan area with the agricultural San Joaquin Valley. The route traverses urban centers, university towns, and rural farmland, providing an arterial link between Interstate 80, Interstate 5, and State Route 99. The corridor serves commuter, freight, and recreational travel and intersects significant transportation corridors and river crossings.

Route description

The route begins near Davis adjacent to UC Davis and proceeds north through Woodland, intersecting with Interstate 5 and carrying traffic toward Sacramento suburbs and Yolo County communities. North of Woodland the highway runs near the Sacramento River, passes close to Sutter County agricultural tracts and enters the city of Dixon, where it crosses Interstate 80 and connects with routes serving San Francisco commuters and Solano County employment centers such as Travis Air Force Base. Continuing northwest, the route skirts the edge of the Suisun Marsh and links with roads toward Vallejo and Benicia before turning northeast toward Sacramento Valley, passing through rural landscapes associated with Central Valley Project water conveyance infrastructure. Approaching its northern terminus, the highway intersects SR 99 near Mendota and provides access to Fresno-area agricultural distribution. The corridor supports connections to Union Pacific Railroad, regional trucking lanes, and intermodal transfer points that feed into the wider California State Highway System.

History

The corridor that became the highway evolved from 19th-century wagon roads serving Gold Rush-era settlements and later 20th-century auto trails linking San Francisco Bay Area ports with inland valleys. Early improvements were driven by agricultural expansion tied to projects like the Central Valley Project and the growth of UC Davis, which increased commuter flows between Davis and Sacramento. Designation under the 1964 state highway renumbering formalized the route amid broader changes affecting Interstate Highway System integration and California Freeway and Expressway System planning. Subsequent decades saw bypass construction around towns such as Woodland and grade separations near Interstate 5 to improve freight movement serving Port of Sacramento-linked logistics. Flood control and river levee projects related to Sacramento River Flood Control Project influenced alignment choices and maintenance priorities. Recent history includes pavement rehabilitation funded through Proposition 1B and local regional transportation measures advanced by entities like the Yolo County Transportation District and the Solano Transportation Authority.

Major intersections

- Southern terminus: junction with Interstate 80 near Davis and access to UC Davis Medical Center. - Connection with County Route E8 and local arterials serving Woodland and Yolo County. - Interchange with Interstate 5 facilitating movements toward Los Angeles and Redding via the West Coast route. - Crossings near Dixon providing links to Interstate 80 for travel to San Francisco and Oakland. - Junctions serving access to Travis Air Force Base and connections to Solano County highway network. - Northern terminus: connection with SR 99 in the vicinity of Mendota feeding south toward Fresno and north toward Sacramento.

Future and planned improvements

Planned projects focus on capacity, safety, and resilience with proposals coordinated by agencies including the California Department of Transportation and regional bodies such as the Sacramento Area Council of Governments and Yolo-Solano Air Quality Management District. Improvement concepts include interchange upgrades near Interstate 5 and Interstate 80 to reduce congestion affecting commute corridors to UC Davis and Sacramento State University; widening segments to accommodate truck volumes tied to Port of Oakland-bound freight; and levee and drainage enhancements in coordination with California Department of Water Resources to mitigate flood risk from the Sacramento River. Environmental review processes reference protections for habitats associated with the Suisun Marsh and migratory bird areas managed in part by the U.S. Fish and Wildlife Service. Funding avenues under consideration include state transportation packages, regional sales tax measures, and federal infrastructure grants administered through U.S. Department of Transportation programs.

Related routes and designations

The highway interfaces with several state and federal corridors including Interstate 80, Interstate 5, and State Route 99. Locally, county routes and city arterials connect to commerce centers such as Woodland, Dixon, and Davis. The corridor is part of state systems like the National Highway System and falls within planning jurisdictions of entities such as the California Transportation Commission, the Sacramento Area Council of Governments, and the San Joaquin Valley Air Pollution Control District for portions touching the Central Valley. Designations addressing freight and emergency evacuation alignments reference coordination with Federal Emergency Management Agency floodplain mapping and regional freight strategies tied to ports and rail yards including those operated by Union Pacific Railroad and BNSF Railway.
