    Project Overview


    Anticipated Project Schedule

    Funding

    This $41.5 million project is funded with federal dollars and by OC Go (also known as Measure M), Orange County’s half-cent sales tax for transportation improvements.

    Community Outreach

    As the project continues through the construction phase, we will continue to keep residents, businesses and community leaders informed. We are actively meeting with key groups, homeowners associations and businesses in the area. Please contact us to schedule a presentation or for additional project information.


    Upcoming Construction Activities

    Closures and Detours Map

    Plan your commute around construction with the I-5 Central County Improvements Project Interactive Map. Visit www.octa.net/i5centralmap for information about construction activities and closures.

    NIGHTTIME CLOSURES: MEDIAN BARRIER REMOVAL

    WHAT: Crews continue demolishing the concrete barriers between the carpool lane and regular lanes. The removal of the barriers will make room for a second carpool lane on I-5 between SR-55 and SR-57 to ease congestion and alleviate bottlenecks. This activity can only be done at night and requires closures.

    WHEN: 10 p.m. to 5 a.m. nightly, Sunday, Jan. 12 to Thursday, Jan. 16.

    WHERE:

    • Southbound I-5: Left lanes between the SR-57 connector and Fourth Street
    • Southbound I-5: Carpool lane between Gene Autry Way and First Street
    • Southbound SR-57 carpool connector to Southbound I-5

    NIGHTTIME CLOSURES: ELECTRICAL ACTIVITIES

    WHAT: Contractors are performing electrical work in various areas on I-5 between First Street and SR-22, particularly in the section between Grand Avenue and 17th Street as they wrap up paving and electrical activities in preparation for the opening of the new roadway this Spring. This work can only be done at night and requires closures. Northbound Main Street, 17th Street and Grand Avenue ramps are expected to close intermittently. We encourage you to visit the interactive map for details.

    WHEN/WHERE:

    Monday, Jan. 13 and Tuesday, Jan. 14 from 10 p.m. to 5 a.m.

    • Northbound SR-55 carpool connector to northbound I-5

    Tuesday, Jan. 14 to Thursday, Jan. 16 from 1 am. to 5 a.m.

    • Northbound I-5: Carpool and left lanes between First Street and SR-22

    This work may be loud. Dates and times are subject to change due to inclement weather or unforeseen operational factors.


    I-5/Main Street Carpool Bridge Closed

    The I-5/Main Street carpool bridge was demolished in early August 2019 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 bridge 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.
