I-5 Central County Improvements

Central I5

Project Overview

Current studies suggest, 390,000 motorists travel the I-5 freeway between the SR-55 and SR-57 freeways daily and projected traffic volumes anticipate a 19 percent increase by 2030, bringing the total to 464,000 motorists per day. Caltrans in partnership with OCTA proposes to relieve traffic congestion, eliminate bottlenecks and improve traffic operations on this corridor within the cities of Santa Ana, Orange and Tustin. The project recommends adding a second HOV (High Occupancy Vehicle) lane in each direction and removing the I-5 / Main Street HOV on- and off-ramps.
