Construction Updates
OCTA in cooperation with Caltrans is improving 16 miles of the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605). It also will construct the 405 Express Lanes from SR-73 to I-605. The new express lanes – incorporating the existing carpool lanes and connectors that opened in 2014 – will be two lanes in each direction.
