California’s priciest bridge, still under construction, isn’t meant for cars or pedestrians and has already run up a cost exceeding $100 million.
The Wallis Annenberg Wildlife Crossing towers above the 101 Freeway in Agoura Hills, a suburb of Los Angeles County, and was conceived as a groundbreaking conservation effort.
This innovative, living structure aims to bridge the divide for wildlife hindered by highways and urban development.
Some view it as a visionary project, while others consider it a costly gamble.
The expenses, undeniably significant, continue to escalate.
Originally estimated at around $92 million, the cost has surged to approximately $114 million, a jump of over $21 million.
Plans have also changed, with the initial completion date of 2025 now pushed to late 2026 at the earliest.
Despite its philanthropic backing, taxpayers have footed the majority of the $77 million already spent.
The initiative was sparked in part by the death of P22, the ‘Hollywood Lion,’ who succumbed to injuries after trying to cross the 101.
P22 became famous, partly due to a National Geographic photo capturing him near the Hollywood sign in 2012.
His passing inspired private contributions to the bridge, named after the notable California philanthropist Wallis Annenberg, who passed in 2024.
The concept for a wildlife bridge originated in the 1990s, as research identified the area as a critical point for animals trying to migrate between the Santa Monica Mountains and Simi Hills.
Experts warn that without safe routes, animals like mountain lions may become isolated and inbred.
Governor Gavin Newsom, who initiated the project’s ground-breaking in 2022, hailed it as a template for future projects across California.
The bridge will stretch 210 feet in length and 174 feet in width, supported by 26 million pounds of concrete, with a noise barrier made from up to 4 feet of earth, along with various native plants, rocks, and vegetation.
It might have been wise for California to consider successful examples from elsewhere first.
For instance, Banff National Park in Canada established a network of 40 wildlife crossings on the Trans-Canada Highway back in 1996, costing between $6.2 million and $9.7 million initially.
If initiated today, it would range from $17 million to $20 million considering inflation.
Since their inception, collisions between wildlife and vehicles have dropped by 80 to 90 percent.
In Colorado, there’s also a major wildlife overpass on Interstate 25, constructed for about $15 million and completed in just a year. Another successful $23 million overpass near San Antonio, Texas, also saw positive results.
The usual price range for constructing wildlife crossings in the U.S. falls between $5 million and $20 million.
This Wallis Annenberg Wildlife Crossing, however, stands out with its whopping price tag of $114 million, which is still rising.
Proponents argue its larger size and complexity are necessary due to its location on the urban fringe and the goal of reconnecting an entire ecosystem.
Meanwhile, detractors contend that the project has turned what could be a functional design into something extravagant.
Additionally, a significant distinction exists between California’s approach to bridge-building and that of other regions; California’s structures aren’t singular intersections but part of a broader network.
For example, Banff’s strategy included multiple overpasses, and Florida’s numerous crossings helped stabilize its endangered leopard population. Colorado, too, isn’t focusing on a single showcase but rather establishing a comprehensive system.
