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

Retaining Walls

WHAT: Widening work continues on northbound I-5 between Grand Avenue and 17th Street to accommodate the additional carpool lanes.

As part of the widening, crews are cutting and drilling into the slope adjacent to northbound I-5 and constructing two retaining walls. Crews continue to excavate and install temporary shoring in preparation for the construction of the walls. The temporary shoring supports the existing slope while the new retaining wall is built.

WHEN: Construction activities for the next few weeks are expected to occur during the day, from 6 a.m. to 3 p.m.

K-Rail Placement

In the coming weeks, crews will place k-rail along the shoulder in each direction of I-5 between SR-55 and SR-57. K-rail creates a work area for crews to begin drainage activities.

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.
