An 80-hour full and partial closure of lanes on the 405 Freeway through the Sepulveda Pass got underway Friday night.


Partial and full lane closures were set to begin on the 405 Freeway through the Sepulveda Pass on Friday, Feb. 14, 2014.

Dubbed “Jamzilla,” the closures were slated to affect a six-mile stretch of northbound lanes from Getty Center Drive to Ventura Boulevard.

Work began Friday night at 10 p.m., and was expected to be finished at around 6 a.m. on Tuesday, according to the Los Angeles Metropolitan Transportation Authority.

Southbound lanes were expected to remain open during the day, though transportation officials advised that there may be some lane closures on that side of the freeway at night.

The connector ramps from the 10 Freeway to the northbound 405 Freeway would also be closed, according to Metro.

Because of the construction, transportation officials urged motorists to stay away from the northbound stretch of 405 Freeway over the long Presidents Day weekend.

“Without these diversions, traffic conditions on local streets and freeways within the Southern California region could result in multi-hour delays,” Metro warned on its website.

Most of the full closures were scheduled to occur during overnight and early morning hours.

According to Metro, a full closure of northbound lanes was slated to be in effect during the following times:

  • Saturday, Feb.  15 – 1 a.m. to 6 a.m.
  • Sunday, Feb. 16 – 2 a.m. to 7 a.m.
  • Monday, Feb. 17 – 12 a.m. to 5 a.m.
  • Tuesday, Feb. 18 – 12 a.m. to 5 a.m.

Sepulveda Boulevard through the Sepulveda Pass would remain open during “Jamzilla,” according to transportation officials. It has been designated as an alternate route this weekend, according to the Metro blog post.

The 405 Freeway closures were being enacted to allow crews to finish construction on a new carpool lane.
