The Coming Nightmare on the 405 Fwy

They call it the “I-405 Sepulveda Pass Improvements Project”, but for those of us who travel the 405 from the Westside to the Valley or back, it’s going to be a nightmare for at least 2 days between July 16 and 17. During such time, the southern half of the Mulholland Drive bridge over the 405 will be demolished.

I-405 Freeway Closure Schedule

  • Friday, July 15 as early as 7 p.m.:  ramps and connectors to the freeway begin closing
  • Friday, July 15 as early as 10 p.m.: freeway lanes begin closing to ensure full freeway closure at midnight
  • Saturday, July 16 at 12 a.m. (midnight):  full freeway closure
  • Sunday, July 17 all day:  full freeway closure
  • Monday, July 18 at 5 a.m.:  freeway lanes begin opening
  • Monday, July 18 by 6 a.m.:  ramps and connectors finish reopening

For North bound traffic (i.e., from the Westside to the Valley) the 405 Freeway will be closed between US 101 (the Ventura Freeway) and Getty Center Drive.

For Southbound traffic (i.e., from the Valley to the Westide) the 405 freeway will be closed from the 1-10 Freeway (Santa Monica) to U.S. 101.

Forget about taking Sepulveda Pass as an alternative as it will be closed to all, but local traffic which should be prepared to show id.

The Detour Routes, e.g., the 10 and 101 Freeways, will be worst and probably should be avoided, if at all possible.

The Mulholland bridge actually predates the section of the 405 Freeway it crosses.

The Bridge was completed in 1960 and it would be another two years before that section of the 405 Freeway would be completed. Read the complete story about the bridge here

    Thanks for this, best summary of the actual events I’ve yet seen.

  2. I must be tired. I read that as must show id, like be prepared to check your ego, but show your id.

    Remember the Olympics? Everyone just go to the beach (unless you live in the Valley…then jump in the pool) and relax. Nothing to see here
