I-405 Connector to EB & WB I-105 Reconstruction Project

Project Description:

HAWTHORNE - The California Department of Transportation (Caltrans) has reconstructed the following two connector ramps:

  • The northbound I-405 (San Diego Freeway) connector to eastbound I-105 (Century / Glenn Anderson Freeway) was closed for 14 weeks for reconstruction. It re-opened at 5 a.m. on January 3, 2018.
  • The northbound I-405 connector to westbound I-105 was closed for almost 12 weeks for reconstruction. It re-opened at 3 a.m. on March 24, 2018.
  • El Segundo Blvd. on ramp to northbound I-405 re-opened at 5 a.m. Friday, May 4 after a long-term closure. Thank you Southern California for your patience as we work hard to improve your roadways!
  • The construction crews may work up to seven days per week, 12 hours per day from 7 a.m. to 7 p.m. Expect noise from the demolition work, machinery and construction vehicles during this time.
  • When the connector roads are closed, please use the following detour routes

Westbound Detour Route:

From northbound I-405, exit onto Imperial Highway or Century Blvd. westbound. Drivers on the northbound I-405 originating from points south of I-110 (Harbor Freeway) are advised to take northbound I-405 to northbound I-710 or northbound I-110 to westbound I-105 into LAX.

Eastbound Detour Route:

From northbound I-405, exit Imperial Highway, drive east to arrive at I-105 at the Freeman Ave. on-ramp.

Detour signs will be posted. Motorists should anticipate delays, and are encouraged to plan ahead and use alternate routes. For real time freeway traffic information, please visit Caltrans QuickMap for current information.

The long-term connector closure is part of a $4.3 million roadway and embankment repair project on both connectors of I-105, in the cities of Hawthorne and El Segundo. Griffith Company is the contractor on this project which began in March 2017, and is expected to complete fall, 2018. Caltrans reminds motorists to "Be Work Zone Alert."

Total Programmed Project Costs: $4.385 Million
