ROAD HOURS UPDATED 5/30/25 – Hours Extended Again
Caltrans has received several requests to adjust the hours to access State Route 27/Topanga Canyon Boulevard, given the longer daylight hours in summer and the various events in the canyon.
Thus, as of Friday, May 30, highway will be open from 5 a.m. until midnight with continuing one-way traffic control at the damaged portion of the roadway and pilot cars facilitating traffic.
The highway will be closed fully from midnight to 5 a.m.
As construction continues for the water main, undergrounding and walls, these hours may be changed. We will keep you posted.
Emergency vehicle access and evacuation will always be available during an emergency.
UPDATE: 5/25/25, and 5/27/25
TCB is LIMITED to daytime hours 5:30AM-7:30PM with traffic controls + one-way directional flagging between postmile 2.3 & 2.7 due to ongoing work. Expect delays. No passes needed.
PCH & TOPANGA CANYON BLVD SET TO REOPEN FRIDAY, 5/23/25 at 8 a.m.
Posting: 05/22/2025 – revised 1:45pm
Topanga Canyon Blvd will continue to be one lane in several sections and will have Intermittent Travel Control ( ITC) in place, which means one lane of travel, controlled either by traffic signal or flagmen. Expectations are this ITC will take place at several locations simultaneously over the course of several months, likely till the end of all road work. That end of road work is expected to be completed at calendar years end, at best.
Travel will be slow going. The work will include the building of two retainings walls, slope stabilization, creek runoff rebuilding, utility undergrounding and then repaving. There are 9 areas of concern, of varying degrees, including the Public Works water pipe repair. The Caltrans retaining wall project, at the water pipe exposure area, is the area and project with the most complicated fix and will require the most time to repair.
Repaving of the upper portion of Topanga Canyon Boulevard from just south of Cezanne to Happy Trail will begin June 2, Monday through Friday evenings, 10 PM till 6 AM.
Additional repaving will take place into spring of next year once all roadwork and undergrounding has been completed.
