Starting Monday, October 30, 2017, Canwood Street will be re-opened to through traffic in order to access the Saratoga Hills/Saratoga Ranch communities. The temporary access road will be closed to the general public

The City of Calabasas has prepared a schematic look of the Gateway to the City the Lost Hills Road Interchange. The new bridge will include architectural and aesthetic elements of the City Hall and additional artistic details such as sculptures of a red tailed hawk, the City logo, and hilly motif of our beautiful area, for Calabasas residents and visitors to enjoy.

The new bridge is projected to be fully open for traffic in March 2018. The City, the contractor, Security Paving Co., and the construction management team, presented by Parsons, are working together to minimize delays and to expedite work on the project.

Below are a few major milestones of the project:

October 2017 - opening of the west side of the bridge
October 2017 - closure of temporary access road and Canwood Street opening
November 2017 - demolition of the old bridge
March 2018 - completion of the east side of the bridge
July 2018 - installation of landscaping and project completion

The major milestones might be delayed by rainy weather and/or unexpected conditions. The project website will be updated regularly to keep you informed about the project progress and any changes in the schedule.



Lost Hills Project Presentation

The City would like to ask/advise that during the current phase of construction for the Lost Hills Interchange project, to best avoid the construction area please utilize the US Hwy 101 North and Southbound Liberty Canyon Off-Ramps and the adjacent Agoura Road, to deter traffic congestion.

Safety Bulletin - Defensive Driving

The Lost Hills/US 101 Bridge and Interchange project is a $25 million overhaul of the Lost Hills Road/US 101 interchange. It will involve widening the Lost Hills Road overpass to five lanes, providing improvements to the on/off ramp design onto US 101, and ensure safe access for all pedestrians. The cost of the project will be funded by Measure R funds.

For up to date information on road closures, project progression and traffic please visit the City of Calabasas Facebook Page, and leave questions and comments.
