Wildlife Crossing Disrupts Agoura Road Commute
- Construction of a new wildlife crossing will cause lane closures and intermittent stoppages on Agoura Road during peak commute times. - Work centers around the proposed wildlife bridge near Kanan-Dume Road and Agoura Hills' eastern foothills, creating detours and single-lane traffic. - Officials say the bridge will reduce animal-vehicle collisions, but commuters should expect months of delays and detours (patch.com).
Agoura Road in Agoura Hills is now closing on weekdays through July 1 as crews build the Wallis Annenberg Wildlife Crossing over U.S. 101. (dot.ca.gov) Caltrans said the full closure covers Agoura Road between Rondell Street and Hydepark Drive, Monday through Friday from 7 a.m. to 5 p.m. No through traffic, including motorists, cyclists, or pedestrians, is allowed inside the work zone during those hours. (dot.ca.gov) Drivers are being detoured onto U.S. 101 between Chesebro Road and Liberty Canyon Road. Pedestrians and cyclists can use a free shuttle every 30 minutes, with stops at Dorothy Drive and Chesebro Road on the west side and Liberty Canyon Road and Agoura Road on the east side. (dot.ca.gov) The current closure is for abutment walls, the concrete supports that hold up the ends of the bridge. Earlier phases used one-lane traffic controls starting in September 2025 before the project shifted to full daytime closures. (dot.ca.gov; dot.ca.gov) The bridge is being built at Liberty Canyon to reconnect habitat split by the 101 Freeway between the Santa Monica Mountains and the Simi Hills. The Santa Monica Mountains Conservancy says the crossing is a public-private partnership involving Caltrans, the National Park Service, the National Wildlife Federation, and other agencies. (smmc.ca.gov) National Park Service-backed research at the site has tracked bobcats, coyotes, and mountain lions for more than 25 years. Project backers say roads and development have turned habitat into isolated patches, blocking animal movement and reducing gene flow, or the mixing needed to keep populations healthy. (nps.gov; 101wildlifecrossing.org) State officials said in February that the crossing had received the funding needed for completion, and project supporters have described it as the first wildlife overpass of its kind in California. The governor’s office said the structure is intended to cut wildlife-vehicle collisions while allowing animals to move across the freeway corridor. (gov.ca.gov) The project has also grown more expensive and taken longer than first projected. Caltrans said in August 2025 that the crossing was a $92 million project expected to wrap up in 2026, while more recent reports have put the cost at $114 million and the opening in late 2026. (dot.ca.gov; ktla.com) For commuters, the immediate change is simpler than the conservation case: weekday daytime trips across that stretch of Agoura Road now require a freeway detour, and the city has posted the closure notice on its front page.
