  • Project Overview

    OCTA and the California Department of Transportation (Caltrans) District 12 added a new, four-mile westbound general purpose lane to State Route 91 between State Route 57 and Interstate 5. The new lane reduces choke-point conditions from the southbound 57 freeway to westbound 91, providing a smoother and more efficient transition for motorists. Additionally, motorists can now connect from SR-57 to I-5 without changing lanes on the 91.

    With the improvements, this pivotal six-mile stretch of SR-91 now includes four general-purpose lanes and one carpool lane. The existing carpool lane is striped to allow continuous access by drivers, which studies have shown reduces accidents and air pollution.

    Beyond the new lane, the project reconstructed 10 westbound on- and off-ramps which provide dual exit lanes, added capacity and dedicated turn lanes to reduce back-up on the freeway and streamline transitioning from the freeway to local streets. The improvement project also constructed 12 retaining and-or sound walls, and widened bridges at State College Boulevard, Acacia Street, Raymond Avenue, the Metrolink Overcrossing, Euclid Street and Brookhurst Road. Lanes and shoulders were also restriped and standardized within the project limits. Additionally, overhead signage and barriers provide enhanced visibility and safety for motorists.

    The SR-91 Westbound Lane Widening Project is a delivered promise made possible by Measure M. Passed by nearly 70% of voters in 2006, Measure M is Orange County’s voter-approved half-cent sales tax for transportation, sets aside 43 percent of revenues collected for freeway improvements.

  • About the Project Area

    Located in northern Orange County, the Riverside Freeway (SR-91) is one of the region’s most vital, but also most congested commuter and commercial corridors. Everyday more than 300,000 motorists drive it to get to work, school, home and other essential destinations. And by 2035, more than 425,000 drivers are expected to travel the 91 daily. The 91 Freeway connects communities in Riverside County with employment centers in Orange County. It also serves as a “bridge” that links commercial trucks transporting good and products from the ports of Los Angeles and Long Beach to key local, regional and even national markets. Orange County visitors and locals alike, also drive SR-91 to get to world-class attractions and special events at Anaheim Stadium, The Honda Center, Disneyland, Knott’s Berry Farm and other destinations. In short, SR-91 helps drive our economy and quality of life. This is why building “A Better 91” to keep the 91 Freeway moving, will help keep Orange County moving.

    • Bridges
      As part of the project, construction crews widened six bridges in the westbound direction at: State College Boulevard, Acacia Street, Raymond Avenue, Metrolink Crossing, Euclid Street, and Brookhurst Road. In an effort to maximize safety and minimize traffic impacts, demolition work of overpasses largely took place during the night. 
    • Walls
      More than 10 retaining and/or sound walls were built between State College Boulevard and Brookhurst Road as part of this project. Existing walls at Acacia Street, adjacent to Houston Avenue between Euclid Street and Brookhurst Road, and along the westbound 91 on-ramp at Brookhurst Road were demolished to make room for the new lane and were reconstructed at a height equal or greater than the previous wall. 
    • Houston Channel
      The Houston Channel is a storm drain facility owned and operated by the Orange County Flood Control District (OCFCD) that runs above ground along the northern side of the 91 Freeway. To make room for the new lane and shoulder, crews reconstructed a limited section of the Houston Channel between Euclid Street and Brookhurst Road to an underground channel with the carrying capacity required by the OCFCD.

    Funding for the $61 million freeway improvement project is provided by state and local sources, including Orange County’s Measure M and the State of California’s Transportation Corridor Improvement Fund (TCIF).
