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.

Trancas Creek Bridge Replacement Project

Schedule TBD

The California Department of Transportation (Caltrans) District 7 proposes to replace the Trancas Creek Bridge on Pacific Coast Highway (PCH/SR-1) in Malibu due to the age of the bridge and its vulnerability to erosion.


Caltrans held a public hearing in May 2017 and accepted written comments through June 2017, including a comment letter submitted by the City of Malibu. In July 2017, Caltrans announced it had selected Alternative 3 (Long Bridge) for the project, and also released the Mitigated Negative Declaration / Finding No Significant Impact.

Project details are available at DOT.CA.gov/D7/Projects/Trancas.


Malibu Canyon Road Pole Replacement Project

April 2017 to March 2018

Completed march 2018

In order to improve safety and reliability, and comply with California Public Utilities Commission Requirements, Southern California Edison (SCE), along with various telecom companies, removed 82 poles, including existing poles and guy wires, and installed 65 new poles along a 3.5 mile stretch of Malibu Canyon Rd, between Harbor Vista Dr and Piuma Rd. The project was completed on schedule at the end of March 2018.

Las Virgenes Road Scenic Corridor Widening Project

July 2015 to May 2017

In July 2015, the City of Calabasas began work on its Las Virgenes Road Widening Project, between Lost Hills Road and Agoura Road (near the 101 Freeway). The project, which is expected to be completed in May 2017, will require intermittent lane closures that may cause delays through the project area, impacting traffic times for commuters on Malibu Canyon Road The project includes road widening to two travel lanes in each direction, two new traffic signals, bike lanes, new sidewalk, landscaping and tree maintenance, new crosswalks, and the relocation of power poles.

As of early 2017, the project is progressing with roadwork and utility installation/undergrounding. Two northbound lanes, one southbound lane, and the Willow Glen St traffic signal will be completed and activated by the end of April 2017. SCE is scheduled to remove power poles during the week of May 22, after which the road will be finished and capped with rubberized asphalt, concluding the project.

Project updates, including lane closures, are posted to the project webpage on the Calabasas website.

Topanga Canyon Utility Undergrounding Project

July 2015 to April 2018

In July 2015, the Los Angeles County Department of Public Works began work on a project to underground utilities in Topanga Canyon. The projects will improve the visual look of the area, and enhance public safety by removing most utility poles and placing utility lines underground. Utility service from the main utility lines into residential and business properties can be undergrounded up to 100 feet from the road right-of-way.

While the majority of the civil work was completed by early 2017, SCE estimates the project will be extended through March or April 2018, due to long lead times for some required materials. This also takes into account a moratorium on construction from Thanksgiving through the end of the year.

Motorists can expect intermittent traffic delays on Topanga Canyon Boulevard over the construction period. Work hours are Monday through Friday, 9:00 AM to 3:00 PM, with no work taking place on weekends, major holidays, or Red Flag days. Project details and updates can be found on the County's project webpage.

Agoura Road Widening Project
January 2015 to Mid-2017

This City of Agoura Hills project, which began in January 2015, will widen a 2.2 mile stretch of Agoura Road, from two to four lanes, between the city's westerly limits and Kanan Road Once complete, the project will improve the roadway's function to serve as an emergency alternative to the Ventura Freeway (US 101), create a consistent design, compatible with the existing roadway, and improve traffic flow.
