Carmageddon 2 Closures: Alternate Route Maps To Help Plan Your Weekend

The 405 expansion project otherwise known as "Carmageddon 2" begins this Friday, Sept. 28. with ramp closures starting at 7 p.m. and lane closures starting at 10 p.m. By midnight, the I-405 freeway will be completely closed between the I-10 and U.S. 101 until Monday at 6 a.m., cutting off the biggest North-South artery in the city for 53 hours.

While officials are laying off the apocalyptic messaging this time, the 2012 closures could result in more congested traffic than last year. Contractors have to accomplish 30 percent more work in the same allotted time, and the closure's September timing means that UCLA students are back in town for school.

There are also several mass events around town, like a triathlon, Dodger games and concerts at the Hollywood Bowl that will result in either additional road closures or heavier surface street traffic.

Officials recommend using public transportation, walking or biking to eat, play and shop locally -- but if you must drive, here is the Carmageddon 2 schedule and alternate routes and maps that will help you plan your weekend.

Carmageddon 2 Schedule

Friday, Sept. 28
  • 7 p.m.: ramps start closing
  • 10 p.m.: freeway lanes start closing
  • Midnight: I-405 will be fully closed
Saturday - Sunday, Sept. 28-29 Monday, Oct. 1
  • 5 a.m.: 405 re-opens

Local Alternate Routes
  • Sepulveda Blvd. will be open from the Valley to the Westside, which means drivers will have access to southbound 405 after the Getty Center entrance. However, Sepulveda Blvd. will only be intended for local access, and it isn't meant to serve as a detour for the 405.
  • Other canyon routes that connect LA to the Valley include Beverly Glen Blvd., Benedict Canyon, Coldwater Canyon and Laurel Canyon.
  • For freeway routes to Santa Monica, Orange County, LAX, Santa Barbara, the Valley and the Inland Empire, check out the map below. To see the routes in greater detail, click here [PDF].
