    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

    BRIDGE DEMOLITION PREPARATION & MAIN STREET LANE CLOSURES

    WHAT: To prepare for the demolition of the I-5/Main Street carpool ramp set for mid-July, southbound Main Street will be reduced to two lanes to create a work area for the removal of the lost deck (wood framing system inside the bridge), ramp demolition and construction of a bridge barrier. These activities require closing two lanes to restripe lanes and set k-rail for half a day. Once completed, two through lanes will remain open to traffic on southbound Main Street for approximately six months.

    WHERE:

    • Southbound Main Street in Santa Ana from Walkie Way to the I-5/Main Street carpool ramp.

    WHEN:

    • One lane open: 5 a.m. to noon Monday, June 17.
    • Two lanes open: Monday, June 17 for approximately six months.

    RETAINING WALLS

    WHAT: Crews are scheduled to perform daytime concrete pours behind k-rail for the new retaining walls along northbound I-5. No lane or ramp closures are expected.

    WHERE: Northbound I-5 between the Grand Avenue on-ramp and the 17th Street off-ramp.

    WHEN: 6 a.m. to 3 p.m. Monday, June 17 and Thursday, June 20.

    DRAINAGE ACTIVITIES

    WHAT: The outside lanes and ramps at various locations are expected to close for crews to set k-rail and install drainage, which can only be done at night. Visit www.octa.net/i5centralmap for the latest closure information.

    WHERE: Northbound and southbound I-5 between SR-55 and SR-57


    WHEN: 10 p.m. to 5 a.m. Thursday, June 20.

    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.
