The Riverside County Transportation Commission (RCTC), in collaboration with Caltrans, the City of Corona, the Riverside Transit Agency (RTA), and Metrolink, is proposing the 15/91 Express Transit Connector (ETC) Project. The project aims to improve transit connectivity and high-occupancy vehicle (HOV) access between the 91 Express Lanes and the Corona-North Main Metrolink Station, Corona Transit Station, and Park & Ride Lot. Alternatives currently under consideration range from direct access ramps (DAR) to freeway access openings via re-striping.

The 15/91 Express Transit Connector would:

• Establish a connection to bus and rail transit and Park & Ride Lot facilities for buses on the 91 Express Lanes.
• Enhance transfer options between bus services, regional rail, and local routes.
• Improve access for HOVs to the Express Lanes.
• Encourage the use of public transit and carpooling to reduce vehicle miles traveled.

The Corona-North Main Metrolink Station is a key transportation hub that serves Metrolink, RTA, the Corona Bus Transit Center, and Park & Ride users. Its location near 91 and I-15 interchange makes it a central transit point. Currently, buses and vehicles in the 91 Express Lanes cannot access the station directly. The proposed 15/91 ETC would improve transit connectivity and enhance access for HOVs between the lanes.
