Agoura Road in Agoura Hills is closed on weekdays through July 1 between Rondell Street and Hydepark Drive for work on the Wallis Annenberg Wildlife Crossing. (dot.ca.gov) Caltrans said the closure began Monday, April 20, 2026, and runs Monday through Friday from 7 a.m. to 5 p.m. No through traffic is allowed during work hours, including cars, bicycles, and pedestrians. (dot.ca.gov) Drivers are being detoured onto U.S. 101 between Chesebro Road and Liberty Canyon Road. Caltrans said shuttle service for pedestrians and cyclists is running every 30 minutes during closure hours, and bus stops inside the work zone have been moved temporarily. (dot.ca.gov) The road work is for abutment walls, the concrete supports that hold up the ends of a bridge. Those walls are part of the crossing’s second construction stage, which extends the project over Agoura Road and adds utility relocation, earthwork, and habitat restoration. (dot.ca.gov 1) (dot.ca.gov 2) The larger structure is a vegetated bridge over U.S. 101 at Liberty Canyon, built to reconnect habitat split by the Ventura Freeway. Caltrans said the freeway has become a barrier for mountain lions, bobcats, gray foxes, coyotes, and mule deer moving between the Santa Monica Mountains and the Simi Hills and Santa Susana Mountains. (dot.ca.gov) For mountain lions, that isolation has meant inbreeding, territorial fights, and low genetic diversity in the Santa Monica Mountains population, according to Caltrans. The agency said the crossing is intended to let animals move safely across the freeway and reduce wildlife-vehicle collisions. (dot.ca.gov) Caltrans describes the project as the largest wildlife crossing of its type in the nation. The bridge over U.S. 101 is about 210 feet long and about 174 feet wide, and the total programmed cost is about $92 million. (dot.ca.gov) Stage 1 construction over the freeway started in mid-2022 and was completed in June 2025, Caltrans said. Stage 2 began in 2025 and is scheduled for completion in 2026, with the National Wildlife Federation describing the site as the world’s largest wildlife crossing and offering public tours during construction. (dot.ca.gov) (101wildlifecrossing.org) The closure on Agoura Road is one of the last big disruptions before that buildout finishes. For now, the message for anyone using that stretch is simple: weekdays mean detours until July 1. (dot.ca.gov)
