Purpose This corridor provides for the upgrade of Interstate 710 and ancillary routes to serve the industrial ports of Los Angeles and Long Beach as well as facilitate improved traffic flow for trucks and cars along the freeway between California 60 and the port areas. Improvements Proposed improvements may include but are not limited to: Reconstructing Interstate 710, much of which was initially constructed in the 1950s and 1960s Upgrading the freeway to modern Interstate Highway standards Adding capacity to Interstate 710 to accommodate increased truck traffic and to extend design life Separating truck and auto traffic Revising older interchange and merge designs Status This corridor is partially funded through a variety of funding sources. It is not fully funded, and aspects of the planned upgrade of the corridor are controversial, especially given the proximity of the Los Angeles River and residences.
