Overview Tab Content:

  • Motorists frequently experience traffic congestion on the I-5 freeway between SR-55 and SR-57, and research indicates that delays likely will increase. According to recent studies, 380,000 motorists travel this route every day. By 2035, that daily number is expected to rise to 400,000 – an increase of 7 percent. Caltrans, in partnership with OCTA, is adding a second carpool lane in each direction to relieve traffic congestion, alleviate bottlenecks and improve traffic operations on this corridor within the cities of Santa Ana, Orange and Tustin. The project also includes removing the I-5/Main Street HOV on- and off-ramps.
