  • SR-91 Westbound Lane Addition Project (I-5 to SR-57)

    SR-91 Westbound Lane Addition Project header

    This project was completed in 2016.

    The California Department of Transportation (Caltrans) and the Orange County Transportation Authority (OCTA) added a new four-mile westbound lane to SR-91 from approximately I-5 to SR-57 – delivering a better drive through a key stretch between Anaheim and Fullerton. The new westbound lane increased carrying capacity, improved driving operations and relieved traffic congestion along this vital commuter and commerical corridor.
