SR-91 Overview

Overview

Background

The Orange County Transportation Authority (OCTA) and the California Department of Transportation (Caltrans) District 12 are currently implementing the 91 Freeway Improvement Program, a series of projects intended to increase capacity, improve operations and/or relieve congestion on State Route 91 in Orange County. In general, the 91 Freeway Improvement Program will add new general purpose lanes, improve operations, reconstruct and/or realign on- and off-ramps, widen bridges, construct retaining and/or sound walls as necessary, as well as make various other operational improvements along this commuter and commercial transportation corridor.

A Better 91: The Riverside Freeway (SR-91)

Located in northern Orange County, the Riverside Freeway (SR-91) is one of the region's most vital, but also most congested, commuter and commercial corridors.

Every day, more than 300,000 commuters drive it to get to work, school, home and other essential destinations. And by 2035, more than 425,000 drivers are expected to travel the 91 daily.

The 91 connects residential communities in Riverside County with employment centers in Orange County. It also serves as a "bridge" that links commercial trucks transporting goods 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 the 91 to get to world-class attractions and special events at Anaheim Stadium, The Honda Center, Disneyland, Knott's Berry Farm and other destinations.

In short, the 91 helps drive our economy and quality of life. This is why building “A Better 91” is so important. Keeping the 91 moving helps keep Orange County moving.

Today, there are fourteen projects being studied or planned for SR-91. From conception to construction, OCTA, Caltrans and the Riverside County Transportation Commission (RCTC) are working locally and regionally on projects that will add capacity, improve connectivity, increase mobility and enhance safety.

Common Sense Makes Economic Sense

OCTA's commitment to building "A Better 91" not only makes common sense, it makes economic sense. That's why OCTA has made building "A Better 91" a central part of its transportation mission.

Building "A Better 91" helps protect Orange County's quality of life and keeps it on the road to prosperity. For years, OCTA has been leading local and regional efforts to deliver short, mid-term and long-range improvements to SR-91.

From the 91 Express Lanes, to new general purpose lanes and operational improvements, to financing feasibility studies for new transportation facilities altogether, OCTA’s focus and drive to build "A Better 91" for current and future generations is second to none.

OCTA, Caltrans and RCTC finished the $65 million 91 Eastbound Lane Addition Project on schedule and under budget. The project, which added a new, nearly six-mile lane to a pivotal stretch of SR-91 between SR-241 and SR-71, has been a great success, but making improvements to the 91 are far from over.

In March 2013, construction was completed by OCTA and Caltrans on the $75 million 91 Westbound and Eastbound Lane Widening Project, which added a new lane in each direction between SR-55 and SR-241. As a result, getting to Yorba Linda and Anaheim Hills is quicker and easier. The improvements also help commuters making their way to and from Riverside County.

Next Steps

In February 2013, OCTA and Caltrans kicked-off the SR-91 Westbound Lane Addition Project. The project will add a new four-mile westbound lane from SR-57 to I-5, a very congested portion of SR-91 as it nears the Orange County/Los Angeles County line. The project is scheduled to be complete in early 2016.

Most recently, OCTA and Caltrans began construction on the SR-91 Bypass Lane Project between SR-55 and Tustin Avenue. This project will improve traffic at the SR-55/SR-91 interchange by adding a westbound auxiliary lane beginning at the northbound SR-55 to westbound SR-91 connector through the Tustin Avenue interchange in the City of Anaheim. The project is intended to relieve weaving congestion in this area. Construction is anticipated to be complete in early 2016. When completed, these projects will deliver numerous benefits, from new lanes, to reconstructed on- and off-ramps, to standardized shoulders, to widened bridges and new striping.

In early 2015, the SR-91 Improvement Project from SR-57 to SR-55 will begin the Project Approval/Environmental Document phase. During this process, OCTA and Caltrans will study then impacts of proposed build alternatives
