The California Department of Transportation (Caltrans) in cooperation with Los Angeles County Metropolitan Transportation Authority (Metro) are evaluating alternatives to convert the existing high-occupancy vehicle (HOV) lanes to dynamically-priced, high-occupancy toll (HOT) lanes, also called ExpressLanes, in the eastbound and westbound directions of Interstate 105 (I-105) in Los Angeles County from the terminus of the existing HOV lanes west of Interstate 405 (I-405) in the City of Los Angeles to Studebaker Road in the City of Norwalk. The I-105 ExpressLanes Project (Project) limits include the installation of a new overhead tolling system and signage.

The purpose of this Project is to enhance tra­ffic flow; improve trip reliability and travel times; and sustain and manage mobility.

Cities Within the Project Area

This corridor traverses nine cities and unincorporated areas of LA County, including, El Segundo, Hawthorne, Inglewood, Los Angeles, Lynwood, Paramount, South Gate, Downey and Norwalk.


Measure M, the local sales tax passed by LA County voters in 2016, provides $175 million for this Project.
