SR-91 Overview

Overview

OCTA and the California Department of Transportation (Caltrans) District 12 are currently constructing a new, 4-mile westbound general purpose lane on State Route 91 between State Route 57 and Interstate 5.

The new westbound lane will increase capacity, improve driving operations and relieve traffic congestion along this key stretch of westbound SR-91.

In addition to building a new westbound general purpose lane, construction crews will also:

  • Widen six bridges
  • Realign nine ramps
  • Erect new signage and safety barriers
  • Re-stripe and standardize lanes and shoulders within the project limits

About the Project Area

Located in northern Orange County, the Riverside Freeway (SR-91) is one of the region’s most vital, yet congested, commuter and commercial corridors. Everyday, more than 300,000 motorists drive it to get to work, school, home and other essential destinations. By 2035, more than 425,000 drivers are expected to travel the 91 daily. The 91 Freeway connects communities in Riverside County with employment centers in Orange County. It also serves as a “bridge” that links commercial trucks transporting good and products from the ports of Los Angeles and Long Beach to key local, regional and even national markets. Orange County visitors and locals alike also drive SR-91 to connect with world-class attractions and special events at Anaheim Stadium, Honda Center, Disneyland, Knott’s Berry Farm and other destinations. In short, SR-91 helps drive our economy and quality of life. This is why building “A Better 91” to keep the 91 Freeway moving, will help keep Orange County moving.

 

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

OCTA and Caltrans are working together to add a new, four-mile westbound general purpose lane to State Route 91 between State Route 57 and Interstate 5. The new westbound lane will increase capacity, improve driving operations and relieve traffic congestion along this key stretch of westbound SR-91.

 

SR-91 (SR-55 to Tustin Avenue)

Caltrans District 12 and OCTA are currently in construction on the SR-91 Bypass Lane Project. This is the fourth in a series of improvement projects on the 91 Freeway in Orange County. Since December 2010, OCTA and Caltrans have added 18-lane miles to the 91 Freeway between Interstate 5 and State Route 241.

 

SR-91 (SR-57 to SR-55)

Caltrans District 12 and OCTA are expected to begin the Project Approval/Environmental Document (environmental review) phase on the SR-91 Widening Project between SR-57 and SR-55 in late 2014/early 2015. This proposed project will improve traffic flow and operations in both directions along SR-91 within the cities of Fullerton and Anaheim. This project is funded by OCTA’s Measure M Investment Plan – which was passed by nearly 70% of Orange County voters in 2006.

 

91 Project Construction Safety Tips

OCTA and its project partners are underway with construction on State Route 91 which will significantly improve travel operations along throughout Orange County. Travelers can expect temporary lane closures and need to follow the signs and stay alert.

 

91 Freeway Improvement Project (RCTC)

The Riverside County Transportation Commission (RCTC) and project partners are making improvements to the 91 Freeway from Corona to Riverside. Construction on this major freeway improvement project began in early 2014 and new lanes are expected to open in 2017.
