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.
UPDATE! Beginning April 1, 2024, the construction closure list will no longer be posted. However, closure information is available on the Caltrans Planned Lane Closures website: https://lcswebreports.dot.ca.gov/searchdistricts?district=12
For questions about remaining activities, contact the Community Outreach Team at 405project@octa.net.
