I-5 Widening Project Photo

The Orange County Transportation Authority (OCTA), in cooperation with the California Department of Transportation (Caltrans), the City of Lake Forest, the City of Laguna Hills, the City of Laguna Niguel, the City of Laguna Woods, the City of Mission Viejo, and the City of San Juan Capistrano, is proposing to widen Interstate 5 (I-5) between State Route 73 (SR-73) and El Toro Road.  The project limits on I-5 extend from 0.5 mile (mi) south of the SR-73 interchange (Post Mile [PM] 12.4) to 0.2 mi north of the El Toro Road Undercrossing (UC) (PM 18.9).

 
The project purpose is to increase capacity and operations within the project limits; provide extension of the HOV network within a portion of the project limits to increase capacity; improve merging/diverging from freeway ramps and improve ramp intersections where needed; and improve existing auxiliary lanes and add auxiliary lanes where needed to improve weaving operations.

 
The proposed project will add general purpose lanes in each direction on I-5 between Avery Parkway and Alicia Parkway, extend the 2nd High Occupancy Vehicle (HOV) lane from Alicia Parkway to El Toro Road, reestablish existing auxiliary lanes and construct new auxiliary lanes, and improve several existing on- and off-ramps.  The project is currently in the environmental phase.
