The California Department of Transportation (Caltrans) in cooperation with Los Angeles County Metropolitan Transportation Authority (Metro) has completed 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. The Final Environmental Document is available for review. The Final Environmental Document and Project Report Attachments can be found here
