55 Freeway Project

55 Freeway Project Caltrans and OCTA will add one regular lane and one carpool lane in each direction of SR-55.

SR-55 is one of the most heavily congested freeways in Southern California. The average daily traffic is 261,700 vehicles per day and traffic is expected to increase with future demand. SR-55 is a vital corridor connecting Orange County to Riverside and San Bernardino counties and is a major route for accessing key business centers, John Wayne Airport, major shopping destinations and beach cities.
