  • Project Overview

    OCTA and Caltrans District 12 are expected to begin the Project Approval/Environmental Document phase (commonly known as the environmental review phase) on the SR-91 Widening Project between SR-57 and SR-55 in late 2015/early 2016. This proposed project will potentially increase capacity and improve traffic flow and operations in both directions along SR-91 within the cities of Fullerton and Anaheim.

    The Project Study Report/Project Development Support (PSR-PDS) considers the addition of one general purpose lane eastbound between SR-57 and SR-55, and one general purpose lane westbound from Glassell Street to State College Boulevard. Additional proposed features of the project include improvements to the Glassell Street, Tustin Avenue, and Lakeview Avenue interchanges, and freeway-to-freeway connectors from the northbound SR-57 to SR-91. Auxiliary lanes may be added in some segments and reestablished in others within the project limits.

    This project is only funded through the environmental review phase. Design and Construction phases would move forward when additional project funding is identified.

    Funding – Your Measure M Tax Dollars at Work

    The environmental review phase is funded in part by Measure M Program, Orange County’s voter-approved transportation investment plan. To learn more about Measure M projects, click here. The project is also funded through the State Transportation Improvement Program.

    The Environment Review Process

    OCTA and Caltrans conduct the environmental review process as mandated by the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA).

    At the heart of CEQA and NEPA is the public’s interest in the environment. In general, the purpose of the environmental review process is to identify a proposed project’s potentially significant environmental impacts and to develop measures to avoid, minimize or mitigate these impacts to less than significant when feasible and reasonable.
