Gavin Newsom’s $114 Million “Butterfly Bridge”

How the Wallis Annenberg Wildlife Crossing Became a Gigantic California Boondoggle


Agoura Hills, California — High above the roaring 10-lane Ventura Freeway (US-101), where 300,000 cars blast through daily, sits what promoters once hailed as the “world’s largest wildlife crossing.” The Wallis Annenberg Wildlife Crossing — a vegetated concrete overpass spanning 210 feet long and up to 174 feet wide — was supposed to be a gleaming symbol of environmental innovation. Instead, as of early 2026, it stands as a textbook case of government waste: years behind schedule, $21 million over budget, and now priced at roughly $114 million, with California taxpayers shouldering the lion’s share.



Originally estimated at $87–92.6 million when groundbreaking occurred on Earth Day 2022, the project has ballooned amid torrential rains, inflation, tariffs, labor woes, and what critics call poor planning and scope creep. Completion, once promised for 2025, has slipped repeatedly — first to early 2026, now targeted for November or December 2026 at the earliest.


Governor Gavin Newsom personally broke ground and pledged the state would “complete the job within another $10 million” on top of earlier commitments. That promise has been shattered. State funding has climbed to approximately $77 million, including an extra $18.8 million from the California Transportation Commission — all while the state grapples with a $2.9 billion budget deficit (potentially ballooning to $35 billion). Private donors, led by the late Wallis Annenberg and her foundation (which contributed around $25 million), have helped, but taxpayers are still on the hook for the majority of the overrun.

Project leaders like Beth Pratt of the National Wildlife Federation insist “there’s no boondoggle” and that overruns are normal on big infrastructure jobs. They blame two years of record rainfall that turned the site into a “muddy mess,” forcing rework on soil compaction and supports, plus utility relocations and rising material costs. Yet local reporting and watchdog outlets paint a different picture: a jobs program for environmental consultants, complete with soil scientists, fungi experts, “seed scouts,” and even ritual offerings (including human hair) to native plants. One critic dubbed it Newsom’s “$114 Million Butterfly Bridge,” mocking the elaborate native vegetation planted for everything from mountain lions to monarch butterflies.


The stated goal is noble on paper: reconnect fragmented habitats between the Santa Monica Mountains and Simi Hills so isolated mountain lions (a population of roughly 10–15 adults) can cross safely and avoid inbreeding. Roadkill has been a real problem — 32 cougars killed on area freeways between 2002 and 2022. Proponents, including the late philanthropist Wallis Annenberg, called it “environmental rejuvenation.” But at $7–11 million per mountain lion, potentially helped, the math invites ridicule.


Critics point out far cheaper alternatives: translocating a single genetically diverse lion every generation could achieve similar results for a fraction of the cost, according to scientific papers referenced in coverage of the project. For context, Colorado completed a comparable (though smaller) wildlife overpass for just $15 million. Meanwhile, California pours billions into homelessness with little measurable success, and routine infrastructure crumbles.

Social media and conservative outlets have been merciless, labeling it a “bridge to nowhere,” a virtue-signaling photo-op, and yet another example of Sacramento’s misplaced priorities. Even as native plants are finally being laid atop the structure and small creatures are already exploring it, the final phase — extending over Agoura Road — remains incomplete, with more fundraising and potential taxpayer bailouts looming.


The Wallis Annenberg Wildlife Crossing may one day save a few cougars. But as California taxpayers foot the bill for this ever-expanding environmental vanity project, many are asking: At what cost to everything else? In a state drowning in red ink and real human needs, this multimillion-dollar overpass for wildlife has become the very definition of a boondoggle — gigantic in both ambition and failure.
