The Orange County Transportation Authority (OCTA), in partnership with the California Department of Transportation (Caltrans), is improving State Route 91 from State Route 57 to State Route 55. OCTA and Caltrans are working with the neighboring cities of Anaheim, Orange, Placentia and Fullerton.
The project, which is in the design phase, will improve mobility throughout the corridor, reduce weaving and merging between ramps, and improve on- and off-ramps, sidewalks and bike lanes at the Glassell Street, Tustin Avenue and Lakeview Avenue interchanges.
