After opening to the public last weekend, an auxiliary lane project is improving travel conditions and increasing safety for drivers along westbound SR-91 through the SR-55 interchange.
The nearly 2-mile project area spans from approximately Lakeview Avenue on the east to just past Tustin Avenue on the west. Led by Caltrans with assistance from OCTA, the project extended and reconstructed lanes, the Tustin Avenue off-ramp and the Santa Ana River Bridge to provide additional capacity and eliminate extensive merging.
This is the fourth in a series of improvement projects on SR-91 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.
