District 7 Building

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 12 Caltrans districts statewide. District 7 employs nearly 2,800 people with the largest workforce in construction and maintenance, and others in the administration, environmental, design, program/project management, planning, traffic operations, external affairs and right of way divisions.

There are 1,404 Maintenance employees, 1,324 of which work at 50 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 which will assist in decreasing congestion and increasing mobility. On average, the District manages 140 to 150 ongoing construction projects valued at $2.5 billion to $3 billion.

Constructing an interconnecting HOV system continues to be a priority. A seamless HOV system will help to reduce congestion by using freeway capacity more efficiently. As of 2018, District 7 operates 550 HOV lane miles in Los Angeles County and 7.5 lane miles in Ventura County, the most in the state. Currently, 64 HOV lane miles are under construction and 368 HOV lane miles are in the design and planning stages. Significant HOV projects, including the Golden State and Santa Ana freeways (Interstate 5) Corridor Improvement Projects from State Route 134 to State Route 118 in north LA County and from the Orange County line to I -605 in south LA County, and the addition of an HOV lane in each direction of the San Bernardino Freeway (I-10) between I-605 and State Route 57 are currently in construction.

With the passage of the Road Repair and Accountability Act of 2017 (Senate Bill 1), funds will be dedicated to fixing aging roads and bridges, improving goods movement, and reducing traffic congestion. The new transportation bill will generate $54 billion over the next decade, with District 7 projected to receive approximately $2.6 billion for projects in Los Angeles and Ventura counties. The new transportation bill will also support Caltrans’ mission to be a well-rounded 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.
