Document Description
Caltrans, in coordination with the City of Torrance, proposes to improve the operational conditions of the I-405 freeway mainline, and its on-and-off ramps at Crenshaw Boulevard and 182nd Street in the City of Torrance, in Los Angeles County, from post mile 14.4 to 15.6. Existing roadway deficiencies have led to a continued deterioration of AM and PM peak period operational conditions that are creating queuing issues on the freeway mainline and also at on-and-offramps and intersections immediate to the interchange. These deficiencies are compounded by persistent conflicts in turning movements at the ramps and resulting blocking issues.
