The northbound 405 through the Sepulveda Pass between Skirball Center and Ventura Blvd. will be reduced to three lanes, 10pm Friday 4/17 through 5am Monday, 4/20. Also closed are: northbound off-ramp to Getty Center Drive, Skirball Center on-ramp to 405 N. Supposedly the southbound lanes will not be affected, but web sources didn’t agree on this.

If you’re planning on coming on our trip to Bear Divide banding station in the mountains above Sylmar, north of the San Fernando Valley, please take this possible slowdown into account, especially if you’re planning on arriving at the carpool meetup spot 6:45-7:00 am.

I’m not certain that three open lanes at 6:30-7:00 am on the northbound 405 constitute massive tie-ups, but there will be slowing at the least.
