California progresses on world's largest wildlife crossing

Governor Gavin Newsom announced the commencement of the final phase of construction for the Wallis Annenberg Wildlife Crossing, set to be the world's largest wildlife crossing. This significant project in Southern California aims to connect open spaces on both sides of US Highway 101 in Agoura Hills and is projected to conclude by fall 2026.

"Today, the state is beginning the final phase of construction for what will soon be the largest urban wildlife crossing in the world – all thanks to the visionary work of state, federal, and private partners. The Wallis Annenberg Wildlife Crossing will soon protect Los Angeles’ native wildlife and over 300,000 drivers daily, as well as provide a cutting-edge model for urban wildlife conservation," stated Governor Gavin Newsom.

The last phase involves extending the crossing over a two-lane local road with tasks such as earthmoving, restoring natural hydrology, protecting heritage oak trees, and coordinating with agencies to relocate utilities along the freeway corridor.

The initial phase concluded this year with substantial infrastructure work involving millions of pounds of concrete and other materials. Efforts included laying living soil across bridge structures in preparation for planting over 50 native species this fall.

This project was launched on Earth Day 2022 by Governor Newsom through a public-private partnership aimed at protecting and restoring habitats in Southern California. Wildlife crossings are vital for connecting conserved lands and waters that support biodiversity while enhancing transportation infrastructure.

The initiative supports California’s 30x30 targets by fostering habitat connectivity crucial for people and nature to coexist. It also aligns with Governor Newsom's agenda for rapid infrastructure development delivering upgrades and jobs statewide.
