COSTA MESA, Calif.—After nearly six years of construction, express lanes opened Dec. 1 on the 405 Freeway between Costa Mesa and southern Los Angeles County, promoting a faster ride for people willing to pay the toll.
The $2.16 billion project, which began in 2018, added one new lane in each direction as well as express lanes between state Route 73 and the 605 Freeway, a first for Orange County freeways. The project also included upgrades to streets and on- and off-ramps through the cities affected. Crews also reconstructed 18 bridges, some of which include new sidewalks and bike lanes.
