I-5 Managed Lanes Project (SR-55 to OC/LA County Line)

CLICK HERE to visit our external project website

 The I-5 Managed Lanes Project includes a 15-mile section between Red Hill Avenue, south of SR-55, and the Orange/Los Angeles County Line that will address operational deficiencies related to HOV degradation through studies of alternatives that include priced managed lanes (also known as Express Lanes) strategies. The purpose of this project is to improve the overall movement of people and goods along this section of I-5 through the cities of Tustin, Santa Ana, Orange, Anaheim, Fullerton, Buena Park and La Mirada. Currently, the project corridor has three major freeway-to-freeway interchanges at SR-55, SR-22/SR-57 and SR-91 and at least one HOV lane in each direction.

Caltrans is initiating the Project Approval and Environmental Document (PA&ED) Phase through the scoping process. A key component of scoping is public engagement. The scoping period is between May 9, 2022 -- June 8, 2022

Caltrans is the Lead Agency under the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA). Caltrans is preparing an Environmental Impact Report (EIR) pursuant to CEQA and an Environmental Assessment (EA) pursuant to NEPA.

Proposed Alternatives*

The proposed alternatives under consideration include one No Build Alternative and three Build Alternatives. For details regarding the proposed alternatives, please see the Notice of Preparation and/or the PowerPoint presentation below under 'What is Available/Resources'.

*Project scoping was conducted from May 9, 2022, to June 8, 2022. After the project scoping period and reviewing the proposed project alternatives along with screening criteria, the Project Team held meetings on June 20 and June 21, 2022, and determined to remove Alternative 4B from further consideration of the project. With removal of Alternative 4B, Alternative 4A has been retitled "Alternative 4". 

The following screening criteria was used as reasons for removing Alternative 4B from further evaluation is subsequent project development phases:

Right of Way Acquisitions ● Project Right of Way Cost ● Public Input during Scoping ● Community Impacts ● Visual ● Air Quality ● Noise ● Reduced Access to businesses/parks, etc. ● Impacts to bike/pedestrian facilities (permanent & temporary) ● Impacts to Railroads ● Hazardous Materials ● Major utilities relocation

Equity Workshops

* An upcoming 2nd Equity Workshop meeting is currently being planning for January 2023. Stay tuned for further information regarding date, place, and time. 

On Tuesday, Oct. 4 from 6-7:30 pm, Caltrans District 12 hosted an equity workshop titled “Improving Your Commute on the I-5 in Orange County.” 

Orange County residents are the first customers this project should serve. Historically, transportation projects have provided fewer benefits to communities of color and underserved communities. This workshop was specifically designed to welcome voices from the communities who have experienced disproportionate outcomes from transportation projects and to share how proposed changes to the I-5 could impact and benefit day-to-day life so Caltrans can make recommendations to improve the project.

The workshop was held in a simultaneous hybrid format: In-Person: Ponderosa Park Family Resource Center, 320 E. Orangewood Ave., Anaheim, CA 92802; and online at: Zoom, https://bit.ly/I-5workshop
