SR-91 Highway Improvements

SR-91 Highway Improvements

The SR-91 freeway serves travel between Riverside County and Orange County and is one of the most congested freeways in Southern California. Everyday, thousands of Riverside and Orange County residents experience commute times of up to 3 hours to get to work and return home. Currently, SR-91 is carrying more than 280,000 vehicles per day and is expected to increase to more than 425,000 vehicles a day by the year 2025.


RCTC and the Orange County Transportation Authority (OCTA) are also working together to address congestion on the 91. Through the extension of Measure A, Riverside County’s half-cent transportation sales tax, approximately $430 million is available to improve SR-91 in Riverside County. With the passage of Renewed Measure M, Orange County’s half-cent transportation sales tax, approximately $1.5 billion is available to improve SR-91 in Orange County.
