On August 3, 2026, the northbound on‑ramp at Liberty Canyon on the 101 Freeway in Calabasas will close each day through August 7, 2026, from 9 a.m. to 3 p.m., according to California state officials and the City of Calabasas. The temporary shutdown is part of the final phase of construction for the Wallis Annenberg Wildlife Crossing, a project designed to give animals a safe route beneath the heavily traveled highway.
The Wallis Annenberg Wildlife Crossing, now approaching completion, will create a dedicated corridor that lets wildlife move across the 101 Freeway without encountering traffic. Officials say the crossing is a key component of a broader effort to protect regional habitats and reduce vehicle‑animal collisions. By closing the Liberty Canyon on‑ramp during a six‑day window, crews can install the final structural elements and complete necessary grading without disrupting the flow of traffic on the main freeway lanes.
The closure will be in effect each weekday from 9 a.m. until 3 p.m., with the ramp reopening outside those hours. Motorists traveling northbound are advised to plan for the limited access and consider using adjacent ramps or surface streets to reach their destinations during the closure periods. Signage and temporary traffic control measures will be deployed to guide drivers safely around the work zone.
The timing of the work aligns with the overall schedule for the wildlife crossing, which has been under development for several years. Once finished, the crossing is expected to serve dozens of species, from deer and coyotes to smaller mammals, providing a protected pathway that reduces the risk of fatal collisions on one of Southern California’s busiest corridors.
State and local officials emphasized that the short‑term inconvenience to drivers is outweighed by the long‑term safety benefits for both motorists and wildlife. The project reflects a growing commitment in the region to integrate transportation infrastructure with ecological preservation.
The temporary closure of the Liberty Canyon ramp is one of the final steps before the Wallis Annenberg Wildlife Crossing opens to the public, marking a significant milestone in Calabasus’ efforts to balance development with environmental stewardship.
