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, or add a second HOV lane 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.

The I-10 ExpressLanes Extension Project will analyze four proposed alternatives:

Alternative 1: Existing conditions (no build)
Alternative 2: converting the existing high-occupancy vehicle (HOV) lane to a High Occupancy Toll (HOT) lane
Alternative 3: adding an additional ExpressLane/HOT lane in each direction and converting the existing HOV lane to an ExpressLane
Alternative 4: maintain the existing HOV lane and add a second HOV lane in each direction

Status

This project is beginning environmental review, with a formal scoping process starting April 25, 2022, through June 10, 2022. During this time, Metro and Caltrans will accept scoping comments via mail, email, telephone, and the online comment form, as well as at virtual public meetings. The intent of the scoping process is to gather input on the purpose and need for the project, proposed alternatives, environmental issues, local projects that may be proposed in the study area and approaches for community participation. Scoping comments will inform the areas that may need to be addressed by the environmental and technical studies developed in support of the environmental document.

The environmental review phase will encompass two components: the Project Report and the Environmental Document. Metro and Caltrans are developing a Draft Environmental Impact Report (EIR) and a Draft Environmental Assessment (EA) for this project 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.
