    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 in summer 2019. Construction is expected to be completed in early 2021.

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.
