All Santa Clarita commuter bus lines will operate according to their regular schedules. Century City passengers aboard Route 797 should expect delays on Friday evening and Monday morning, due to increased traffic in the area.

In anticipation of traffic delays and closures, the City’s Beach Bus service will travel to Ventura Beach instead of Santa Monica, giving customers the opportunity to visit the Ventura Pier and the adjacent beaches on Saturday, July 16, and Sunday July, 17.

The specific freeway closure boundaries include the Northbound I-405: 10-mile closure between I-10 and U.S. 101; and Southbound I-405: 4-mile closure between U.S. 101 and Getty Center Drive Ramps. On Friday, July 15, ramps along the 10 mile closure will begin to be shut down as early as 7 p.m., and closure of freeway lanes will begin at 10 p.m. to ensure full freeway closure by midnight. The closure will continue until 5 a.m. Monday morning, July 18. Ramps and connectors will be reopened by 6 a.m.

Motorists who must travel through the Los Angeles metropolitan area during this time are advised to use alternate freeways within the region, including the 5, 15, 23, 55, 57, 101, 118, 126, 210, 605 and 710 freeways to bypass the impacted area. In addition, public transportation options are available such as the Metro Rail service within L.A. County and Metrolink servicing the five county Southern California regions.
