I-10 ExpressLanes Extension Project

Metro has a plan to make it easier to get around, with projects to reduce traffic congestion. The I-10 ExpressLanes Extension Project can improve traffic flow and provide additional travel options in LA County.

Overview

Location: San Gabriel Valley

Phase: Environmental Review

Type: Less Traffic

Forecasted Opening: N/A

Caltrans and Metro are evaluating alternatives to convert existing high-occupancy vehicle (HOV) lanes to dynamically priced, high-occupancy toll (HOT) lanes, also called ExpressLanes, in both directions on Interstate 10 (I-10) from the current ExpressLanes end point at I-605 to the Los Angeles/San Bernardino County line.

Status

The project is in the environmental phase with the Environmental Document anticipated for public release in late 2025 which will include a public comment period and public hearings to solicit input.

This phase will encompass two components: the Project Report and the Environmental Document. Metro and Caltrans are developing a Draft Environmental Impact Report (EIR)/Environmental Assessment (EA) in accordance with the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA).

A Project Report, Concept of Operations and a Traffic & Revenue Study are also being prepared.
