District Map

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 statewide districts. The district employs over 2,500 people with the largest group working in construction and maintenance. The remaining employees are distributed among administrative, environmental, design, program and project management, operations, planning, external affairs and right of way divisions.
  The Department’s mission of improving mobility across California
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. The District currently has 114 projects in construction totaling over $1 billion. In addition, as a result of voter approved Propositions 1A and 1B, transportation funding has been implemented and construction has begun on significant projects such as the northbound San Diego Freeway (I-405) High Occupancy Vehicle (HOV) project, the Golden State Freeway (I-5) HOV project from Orange County to the San Gabriel Valley Freeway (I-605) and the addition of HOV lanes on Interstate 5 from Route 134 to Route 118, and the San Bernardino Freeway (I-10) HOV project.
  Constructing an interconnecting HOV or carpool lane system continues to be a priority. The purpose of the HOV program is to reduce congestion by using the capacity of the freeway system more efficiently. As of 2008, District 7 operated 485 HOV lane miles in Los Angeles County, the largest amount in the state. Twenty-nine miles of HOV lanes were under construction and 179 miles were in the design or planning stages.
  Caltrans operates the Transportation Management Center in coordination with the California Highway Patrol (CHP) to rapidly
detect and respond to incidents while managing the resulting congestion. With the help of the latest electronic technologies such as Changeable Message Signs (CMS), closed circuit television and delineators embedded in pavement, motorists using the largest freeway system in the world benefit from a faster, more efficient transportation management network.
