As you may have heard, Carmageddon II is coming up at the end of September. Officials are encouraging Angelenos to "Plan Ahead, Avoid the Area, or Eat, Shop and Play Locally."

The I-405 freeway will be closed as follows during the weekend of September 29-30:

  • Northbound – I-10 to US-101
  • Southbound – US-101 to Getty Center Dr

But why does one of the busiest freeways in the world need to be shut down for a full weekend? Why do we need a Carmageddon II? Metro gives us the answer:

To reduce congestion, improve mobility and increase safety, the I-405 Sepulveda Pass Improvements Project will add a high-occupancy vehicle lane, standardize traffic lanes and improve on- and off-ramps along a 10-mile-long stretch of the freeway between the I-10 (Santa Monica Freeway) and US 101 (Ventura Freeway).

Widening this crucial but congested highway requires rebuilding three overpasses: Sunset Bl, Skirball Center Dr and Mulholland Dr. Each of these overpasses will feature its own improvements. For example, the upgraded Mulholland Dr Bridge would feature:

> Widened bridge
> Widened sidewalks along bridge
> Widened center bridge median
> Designed to latest seismic code

The first Carmageddon demolished the south side of the Mulholland Bridge; Carmaggedon II will take care of the north side.

Help keep cars off the road by attending an event on Metro's list of local activities in your area during Carmageddon weekend.
