    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

    Remaining major structural work includes construction of concrete median barriers and a retaining wall, as well as installation of new overhead signs. In addition, crews will construct a new barrier on the southbound side of the Main Street bridge over the freeway, where it was once connected to carpool ramps. The ramps were demolished last summer. Construction is expected to be completed in early 2021.

    NORTHBOUND I-5 CARPOOL LANE CLOSED THROUGH THE END OF APRIL FOR MEDIAN BARRIER WORK

    As the Interstate 5 Central Improvement Project comes to a near end, crews are finishing the final phases of the project. Crews have shifted the northbound I-5 regular and carpool lanes to the newly widened roadway between Grand Avenue and 17th Street. This road is now open for use and is part of the final design.

    Nighttime Closures: Traffic Shifts on Northbound and Southbound I-5

    WHAT: The northbound I-5 carpool lane between Grand Avenue and SR-22 is expected to close nightly for approximately one month in the coming week. This closure would allow crews to expedite various activities related to the median barrier. Additionally, a long-term closure on the southbound I-5 carpool lane is expected to take place later in the month. More information on these closures will be provided at a later time.

    NIGHTTIME CLOSURES: CONCRETE MEDIAN BARRIER ACTIVITIES

    WHAT: Concrete median barrier activities continue through the end of next week on northbound and southbound I-5 between SR-55 and SR-57. Work includes k-rail adjustment, electrical activities, concrete median installation and concrete barrier and pavement removal, which can only be done at night and requires closures: weather permitting.

    WHEN: 10:30 p.m. to 6 a.m. nightly, Saturday, April 4 to Friday, April 10.

    CLOSURES:

    • Northbound I-5: Left lanes between First Street and SR-22
    • Northbound I-5: Grand Avenue/Santa Ana Boulevard HOV off-ramp
    • Southbound I-5: Grand Avenue/Santa Ana Boulevard HOV on-ramp
    • Southbound I-5: Left lanes between the SR-57 Connector and Fourth Street
    • Northbound SR-55 Carpool Connector to Northbound I-5
    • Southbound SR-57 Carpool Connector to Southbound I-5

    UPDATE: SHORT-TERM CLOSURES ON NORTHBOUND MAIN STREET CONTINUE

    WHEN: Crews continue with daytime prep work for a new traffic signal at the northeast corner of Main Street and Edgewood Road through mid-next week.

    CLOSURES:

    • 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.

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


    Getting to Main Street

    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.
