Caltrans

The California Department of Transportation, commonly known as Caltrans, is the state agency responsible for managing and maintaining California's transportation infrastructure. Established in 1915 as the State Highway Commission, Caltrans evolved into its current form in 1939 to oversee the planning, construction, and preservation of roads, bridges, and other transportation facilities across the state. The agency operates under the California Governor’s Office and is headquartered in Sacramento, with regional offices throughout California to oversee local projects.

Caltrans oversees approximately 41,000 miles of state highways, including major freeways like Interstate 5, Interstate 80, and the Pacific Coast Highway. Its responsibilities extend beyond roadways to include public transit systems, aviation facilities, railroads, and maritime ports. The agency also plays a key role in traffic safety initiatives, environmental sustainability, and emergency response planning, such as managing road closures during natural disasters.

Funding for Caltrans primarily comes from federal, state, and local sources, including gas taxes, vehicle registration fees, and federal highway grants. The agency collaborates with local governments, private contractors, and community groups to ensure projects align with regional needs while adhering to state and federal regulations. Notable programs include the California High-Speed Rail Authority, which Caltrans supports as part of the state’s broader transportation vision.

In addition to infrastructure management, Caltrans conducts research and innovation to improve traffic flow, reduce congestion, and enhance safety. The agency also engages in public outreach to inform residents about construction projects, traffic updates, and policy changes. With a workforce of over 10,000 employees, Caltrans remains a critical component of California’s economy, supporting commerce, travel, and daily commutes for millions of residents.
