    NEW TRAFFIC PATTERN FOR NORTHBOUND I-5

    Crews shifted the northbound I-5 carpool lane and regular lanes to the newly widened roadway between Grand Avenue and 17th Street. The roadway is open to motorists and is part of the final configuration.

    WHAT: Crews continue to conduct prep work for the installation of a new traffic signal at the northeast corner of Main Street and Edgewood Road, weather permitting.

    WHEN: 9 a.m. to 3 p.m. weekdays, ongoing through Friday, March 27.

    WHERE:

    • Right lane on NB Main Street between the NB I-5 Main Street off-ramp and Walkie Way
    • Right-turn only lane from Edgewood Road to Main Street. Motorists will still be permitted to turn left or right onto Main Street.

    NIGHTTIME CLOSURES: ELECTRICAL ACTIVITIES

    WHAT: Crews continue electrical work at various locations on northbound and southbound I-5 between SR-55 and SR-57. This work requires closures, which can only be done at night.

    Northbound I-5: Left lanes between First Street and SR-22 10 p.m. to midnight, Wednesday, March 25 to Friday, March 27

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.
