Once completed, the bridge will be one of the largest urban wildlife crossings in the world, connecting the Simi Hills and the Santa Monica Mountains over a busy, 10-lane freeway.

[12] GPS tracking collars fitted by the researchers show that most mountain lions approach this particular area and turn back without attempting the hazardous crossing of the freeway.

[16] Scientists identified Liberty Canyon as the best location for a wildlife crossing in a 1990 study commissioned by the Santa Monica Mountains Conservancy.

[11][18] The crossing is situated along a wildlife corridor within the Santa Monica Mountains National Recreation Area that consists of thousands of acres of local, state and federally protected lands and stretches northerly from Los Angeles into Ventura County.

[11][21] To encourage use by wildlife, the bridge will have lush but drought-tolerant vegetation with matte materials to deflect bright headlights and insulation to quiet the roar of cars.

[24] The restoration is partially needed because the 2018 Woolsey Fire burned through the wildlife corridor as it was pushed by strong Santa Ana winds in a southerly direction, and crossed the freeway in this area.

[29] In 2014, the National Wildlife Federation, the Santa Monica Mountains Fund, and the #SaveLACougars campaign began to raise money for the project.

[41] A groundbreaking ceremony was held on Earth Day in April 2022 with Governor Gavin Newsom, Wallis Annenberg, wildlife biologists and members of the public along with local, state and federal legislators.
