  • SR-91 Eastbound Lane Addition Project (SR-241 to SR-71)

    This project was completed in 2010.

    The Riverside Freeway (SR-91) Eastbound Lane Addition Project was the first in a series of projects intended to increase capacity, relieve congestion and improve mobility on SR-91. The Orange County Transportation Authority (OCTA), in cooperation with the California Department of Transportation (Caltrans) and the Riverside County Transportation Commission (RCTC), added a lane to the eastbound Riverside Freeway (SR-91) between the Eastern Toll Road (SR-241) in eastern Orange County and the Corona Expressway (SR-71) in western Riverside County. This project length is approximately 6 miles.
