SR-91 Lane Addition Project (SR-55 to SR-241)

This project was completed in 2013.

The Orange County Transportation Authority (OCTA), in cooperation with the California Department of Transportation (Caltrans) and the Riverside County Transportation Commission (RCTC), added 6 miles in the westbound and eastbound directions to the Riverside Freeway (SR-91) between the Costa Mesa Freeway (SR-55) and Eastern Toll Road (SR-241) in eastern Orange County to reduce traffic congestion.

Project Benefits

• Added 6 miles in both directions to SR-91
• Delivered a much needed second eastbound exit lane at the Lakeview Avenue, Imperial Highway and Yorba Linda Boulevard/Weir Canyon Road off-ramps
• Improved safety barriers, lane striping and soundwalls
