The contractor for the Lost Hills Road Interchange project requested lane closures on the mainline SB 101/NB 101 as well as SB on-ramp and off-ramp. Restriping of SB 101 and SB off-ramp confirmed to start on Tuesday (May 31st) night. The mainline work will start at 10PM with two lanes closed through 6AM. On-ramp closures are allowed from 7PM to 6AM.

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.
