Outside Agency Projects

Many projects conducted in and around Malibu by agencies other than the City of Malibu can affect commute time through the construction areas and may cause additional traffic on alternate routes. Motorists should take extra caution when passing through the work zones.

WaterworksTrancas creek crossing Temporary Waterline Project (PHASE ONE)

In November 2020, Los Angeles County Waterworks - District 29 began construction on the Trancas Creek Crossing Temporary Waterline Project (Phase One) on PCH, between Guernsey Ave and Trancas Cyn Rd. Construction includes installation of 800 feet of temporary bypass waterline in the Caltrans right-of-way. Completion is anticipated in May 2021. 

Work hours are 7:00 AM to 4:00 PM, seven days a week. When necessary, the PCH northbound No. 2 lane and shoulder will be closed from Guernsey Ave to the northern limits of the Trancas Creek Bridge (near the first driveway to the shopping center just north of the bridge). This is necessary to tie in the temporary waterline at the two interconnections north and south of the bridge and remove the existing waterline off the inland side of the Trancas Creek Bridge.


This project proposes to restore or replace damaged drainage culverts on Pacific Coast Hwy (PCH / State Route 1 (SR-1) to increase the service life, reduce the risk of plugging, and prevent erosion of the roadway backfill. The project also proposes that the culvert (Bridge No. 53-0030) at Solstice Canyon Creek be replaced to have the capability of fish passage. The project limits are from 0.4 miles south of Temescal Cyn Rd to 0.1 miles north of Tonga St. 

Caltrans, at the City of Malibu's request, held a virtual community meeting on April 29, 2021 to present its upcoming Solstice Creek and Culvert Rehab project in Malibu. Community members were able to ask questions and give their input during the meeting. 

Trancas Creek Bridge Replacement Project Project 

Caltrans is proposing to replace the existing 96-year old, 85-foot wide, 90-foot long concrete bridge, which was constructed in 1927 to span Trancas Creek on PCH in Malibu, with a new concrete bridge, which will be 105 feet wide by 240 feet long. The new bridge will provide two 12-foot traffic lanes, bike lanes, separate pedestrian lanes and 10-foot shoulders in each direction. Northbound and southbound traffic will be separated by a six-foot striped median. In September 2020, the Planning Commission approved the Coastal Development Permit (CDP) for the project, as well as the CEQA environmental document. Construction began in February 2021, and completion is expected in March 2023.

Along with this Caltrans project, the City will construct a new, dedicated right turn lane on westbound PCH at Trancas Cyn Rd. The proposed right turn lane will be approximately 430 feet long and will accommodate right turns onto Trancas Cyn Rd, as well as traffic entering into the Trancas Market shopping center. The City project is funded by Measure R Highway Operational Improvements funds.
