Project Description

The California Department of Transportation (Caltrans), in coordination with the City of Torrance, proposes to improve the operational conditions of the Interstate 405 (I‐405) freeway mainline, and its on‐and‐off ramps at Crenshaw Boulevard and 182nd Street in the City of Torrance, Los Angeles County, from post mile 14.4 to 15.6.

Caltrans is the lead agency under the National Environmental Policy Act (NEPA), and also the lead agency under the California Environmental Quality Act (CEQA). The proposed project is currently listed in the Federal Transportation Improvement Program (FTIP ID: LA0G874), and is included in the 2016‐2040 Southern California Association of Governments (SCAG) Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) [RTP ID: REG0703].

The purpose of the proposed project is to achieve the following objectives:

Alleviate congestion, and improve traffic flow and operational conditions on the Interstate 405 (I‐405) mainline at the Crenshaw Boulevard/182nd Street Interchange, its on‐and‐off‐ramps, and interfacing local arterials in the City of Torrance
Improve safety, and minimize queuing and blocking through the enhancement of confluence areas and vehicular storage on the I‐405 mainline, and through the introduction of new, protected turn movements at on‐and‐off‐ramps and interfacing local arterials
Rebalance regional traffic circulation through an improvement in Level of Service (LOS) on the I‐405 mainline, on‐and‐off‐ramps, and at local roadway intersections, and complementary reductions in delay, out‐of‐direction travel, and Vehicle Miles Traveled (VMT)
