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.

The SR-91/Tustin Avenue Auxiliary Lane Project is completed. There are no further closures or detours as part of the project.
The new lanes on the 91 freeway opened in May 2016, as soon as they were safely available for drivers. Additionally, the Santa Ana River Channel bicycle path reopened and is available to cyclists and pedestrians.
OCTA and Caltrans District 12 relieved congestion and improved operational efficiency on the 91 freeway in the northeastern part of Anaheim by extending a westbound lane from the northbound (NB) SR-55/westbound (WB) SR-91 connector through the Tustin Avenue interchange. In addition, a westbound auxiliary lane from east of the NB SR-55/WB SR-91 connector to the Tustin Avenue off-ramp was reconstructed. Also, the SR-91 westbound Tustin Avenue off-ramp was reconfigured to a dual lane exit and increased ramp capacity to four lanes which help cars more safely and efficiently transition off the freeway.
With the new lanes open, motorists heading westbound on SR-91 past the Tustin Avenue interchange from the NB SR-55/WB SR-91 connector have the option to do so on a general-purpose lane, while motorists exiting at Tustin Avenue are able to do so on an exit-only lane, thereby reducing merging and weaving and improving traffic flow in this area.
These improvements ultimately reduce choke-point conditions between the connector and the Tustin Avenue off-ramp, enhancing safety for motorists. The project area spans about two miles in length from approximately Lakeview Avenue on the east, to just past Tustin Avenue on the west. The new lanes opened to the traveling public in May 2016.
The SR-91/Tustin Avenue Auxiliary Lane Project is the fourth in a series of improvement projects on the 91 freeway in Orange County. Since December 2010, OCTA and Caltrans have added 21-lane miles to the 91 freeway between Interstate 5 and State Route 71.
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. Everyday more than 300,000 motorists 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 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 get to world-class attractions and special events at Anaheim Stadium, The 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.
