    The Orange County Transportation Authority, in partnership with the California Department of Transportation, and coordination with the cities of Orange, Placentia and Anaheim are currently in the design phase of the State Route 91 Widening Project from State Route 57 to State Route 55. Project improvements include adding a new general-purpose lane, improvements to freeway-to-freeway interchanges, widening bridges, improving ramps, as well as making various other operational improvements. The project is being designed in the following three segments:

    • Improvements on Segment 1, which spans from approximately Lakeview Boulevard on the east to the SR-91/SR-55 interchange on the west, will include realigning the westbound on-ramp to direct traffic to westbound SR-91 and adding a new on-ramp from the Lakeview Bridge connecting directly to SR-55. Segment 1 also includes the replacement of the Lakeview Bridge.
    • Improvements on Segment 2, which spans from the SR-91/SR-55 interchange to the SR-91/SR-57 interchange on the west, will include adding a general-purpose lane in the eastbound direction and replacing bridges at Karemer Boulevard/Glassell Street and Tustin Avenue.
    • Improvements on Segment 3, which spans from the SR-91/SR-57 interchange to approximately State College Boulevard, will include bettering weaving operation from westbound SR-91 to both northbound and southbound 57 and adding an auxiliary lane from SR-57 to Raymond Avenue. Segment 3 will also include the replacement of the La Palma Avenue bridge.

    Given the scope and magnitude of the project, Final Design is a multi-year process with milestones set at 35%, 65% and 95%. Currently, Final Design is estimated to be completed for all three segments in September 2023. Once Final Design is complete, and funding is secured, construction will start on the project.

    Per the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), OCTA and Caltrans District 12 prepared and adopted an Initial Study with Mitigated Negative Declaration/Environmental Assessment with Finding of No Significant Impact (IS with MND/EA with FONSI) for this project.

    This Final Environmental Document identifies the Build Alternative as the Preferred Alternative and provides responses to the Draft IS/EA comments received during the public circulation period. The Preferred Alternative will add one general purpose lane on eastbound SR-91 between SR-57 and SR-55. In addition, the proposed project will make operational improvements including reconstructing ramps, bridges and connectors, from west of State College Boulevard to east of Lakeview Avenue.

Public Participation and Community Engagement

At the heart of the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA) is the public’s interest. And at the center of OC Go (formerly known as Measure M) is a commitment to the taxpayer.

Consistent with these public policy values, OCTA and Caltrans are implementing a public information and community engagement program that not only complies with, but exceeds public information mandates under CEQA and NEPA.

Throughout the environmental study process, OCTA and Caltrans are sustaining a multimedia public communications and community engagement program intended to generate project awareness as well as facilitate public participation and comment.

In addition to the project webpage, the communications and engagement program includes:

  • Noticing and canvassing
  • Public information and public hearing meetings (Open House format)
  • Email notices to elected officials
  • Social media alerts
  • Constituent services
