The California Department of Transportation (Caltrans) is responsible for planning, design, construction, maintenance and operation of the state highway system. District 7, which includes Los Angeles and Ventura counties, has the second largest workforce of the 12 Caltrans districts statewide. District 7 employs nearly 3,140 people with the largest workforce in Construction and Maintenance, and others in the Administration, Environmental, Design, Program/Project Management, Planning, Traffic Operations and Safety, External Affairs and Right of Way divisions.

There are 1,364 Maintenance employees, 1,179 of which work at 67 field offices that maintain safety features, clear incidents and support law enforcement; preserve and repair pavement, sidewalks, drains, bridge decks and railings; repair electrical systems, lights, signs and road markers; remove litter, graffiti and debris; and maintain sprinkler systems, plant and beautify landscaping.

The Department’s mission of providing a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability is evidenced in all District 7 activities. Several regional projects are currently in the planning process or underway that will assist in enhancing mobility. On average, the District manages 212 ongoing construction projects valued at over $2 billion.

Constructing an interconnecting HOV system continues to be a priority. A seamless HOV system will help to move people better by using freeway capacity more efficiently. As of 2024 District 7 operates 509.8 HOV lane miles in Los Angeles County and 7.5 lane miles in Ventura County, the most in the state. Currently, 27.4 HOV lane miles are under construction and 141.7 HOV lane miles are in the design and planning stages. Significant HOV projects include the I-105 HOV to Express Lane Conversion Project, which ranges from Imperial Highway/Sepulveda Boulevard Intersection (west of I-405) in the City of Los Angeles, to Studebaker Road (east of I-605) in the City of Norwalk, in Los Angeles County; and the widening of I-5 to accommodate an HOV lane in each direction between SR-14 and Parker Road, in Los Angeles County.

Since the passage of the Road Repair and Accountability Act of 2017 (Senate Bill 1 [SB-1]), funds have been dedicated to fixing aging roads and bridges, improving goods movement, and reducing traffic congestion. The new transportation bill will generate $54 billion with District 7 already receiving $1.3 billion for the State Highway Operation and Protection Program (SHOPP), and an annual maintenance SB 1 allocation of $48 million. The transportation bill also supports Caltrans’ mission to be a multi-modal transportation agency by expanding transit, bicycle, and pedestrian friendly opportunities.

Caltrans operates the Los Angeles Regional Transportation Management Center in partnership with the California Highway Patrol to rapidly detect and respond to incidents while managing the resulting congestion. With electronic technologies such as Changeable Message Signs, closed circuit television, fiber optic lines and wire loop detectors embedded in pavement, motorists using the largest freeway system in the world benefit from a more efficient transportation management network.
