    Upcoming Construction Activities

    UPDATE: I-5/MAIN STREET CARPOOL RAMP DEMOLITION MOVED TO EARLY AUGUST

    Demolition of the I-5/Main Street carpool ramp in Santa Ana is now scheduled for early August. In anticipation, crews will continue to remove the lost deck (wood forms used in the construction of the bridge) and excavate the roadway between the two retaining walls on the ramp portion of the structure. More details, including specific closures and detours, will be provided in the coming weeks.

    The demolition will require a full street closure of Main Street, as well as various on- and off- ramps and a portion of I-5 between SR-55 and SR-57. Once finalized, all detour and closure information will be available on the project's closures and detours map.

    RETAINING WALLS

    Crews are making progress on two retaining walls along northbound I-5 between Grand Avenue and 17th Street and will continue work as they prepare for a daytime concrete pour for the week of July 15.

    CONCRETE POUR FOR DRAINAGE INSTALLATION

    WHAT: Daytime drainage installation continues behind k-rail. Next week, crews are expected to pour concrete for drainage installation near the Main Street on-ramp, which can only be done at night. The outside lanes and ramps at various locations are expected to close to allow crews to perform this work.

    WHERE: Southbound I-5 between SR-55 and SR-57.

    WHEN: 10 p.m. to 5 a.m. Thursday, July 18.

    Please be advised, this work may be loud. Dates and times are subject to change if there is inclement weather or unforeseen operational factors.


    I-5/Main Street Carpool Ramp Closed

    The I-5/Main Street carpool ramp was permanently closed on Tuesday, April 9. The ramp will be demolished this summer to make room for a second carpool lane on I-5 between SR-55 and SR-57. Motorists who normally use the Main Street carpool off-ramp can check out our Getting to Main Street map.

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.
