Orange County, CA
Project Value: $1.2B (DB)  

Orange County Transportation Authority (OCTA) in cooperation with the California Department of Transportation (Caltrans) is improving 16 miles of freeway on the San Diego Freeway (I-405) between State Route 73 (SR-73) in Costa Mesa and Interstate 605 (I-605) near the LA County Line. The project includes adding one regular lane in each direction from Euclid Street to I-605 and making improvements to freeway entrances, exits, and bridges. It also will construct the 405 Express Lanes, two lanes in each direction from SR-73 to I-605. The new express lanes, incorporating the existing carpool lanes and connectors that opened in 2014, will give solo drivers the choice to speed up their commute for a toll, and carpoolers may ride in the lanes for free.
