Decades-Long Highway Fight Ends with Victory for Red Cliffs NCA

Federal agencies to reject destructive highway proposal, safeguarding critical tortoise habitat and recreation access

St. George, UT – Yesterday, the Bureau of Land Management (BLM) and U.S. Fish and Wildlife Service (FWS) signed a Record of Decision to deny a right-of-way for the four-lane Northern Corridor Highway through Red Cliffs National Conservation Area (NCA) in southwestern Utah near Zion National Park.


“For the seventh time, the agencies have once again concluded that punching a high-speed four-lane highway through a National Conservation Area and critical habitat for the threatened Mojave desert tortoise undermines both the habitat needed for the tortoise to survive and the purposes of the congressional designation as an NCA,” said Todd C. Tucci, senior attorney with Advocates for the West and counsel for conservation groups. “We congratulate the agencies in acknowledging both the broad public opposition to the highway, and the underlying requirement to manage this NCA for conservation and recreation.”


Yesterday’s decision confirms the federal agencies’ rejection of the Northern Corridor Highway project, which would have torn through critical habitat for the imperiled Mojave desert tortoise, violated five bedrock environmental laws, damaged iconic scenic vistas, disrupted treasured outdoor recreation opportunities and set a dangerous precedent for developing federally protected conservation areas across the U.S. According to the final Supplemental Environmental Impact Statement (SEIS), the Northern Corridor Highway is a poor option for the St. George community, as it would increase fire probability and frequency, result in permanent loss to designated critical tortoise habitat, spread noxious weeds and invasive plants and adversely impact the highest number of cultural and historical resources of all considered alternatives.


This long-anticipated Record of Decision marks the conclusion of the agencies’ final SEIS, released on November 7, 2024, and is the result of a decades-long fight from local residents, conservation organizations and outdoor recreationists to keep the highway out of the NCA.


While this decision is a significant victory for public lands protection nationwide, it does not change the fact that world-class recreation and critical species habitat within the Greater Moe’s Valley Area—a treasured area south of the NCA—remains at risk of development. Roughly half of the lands within the Greater Moe’s Valley Area are managed by the Utah Trust Lands Administration and lack long-term conservation protections.

Below are statements from Utah-based and national organizations on today’s decision:

Holly Snow Canada, Executive Director, Conserve Southwest Utah:

“We are very encouraged by this decision, which reaffirms decades-long local agreements to protect Red Cliffs. Finally, we can put an end to the wasteful use of taxpayer dollars on an unlawful and outdated highway idea that would cause significant harm to the people, plants, and wildlife of Washington County. Conserve Southwest Utah remains steadfast in our mission to protect the public lands, water and livability of our desert home. We are committed to safeguarding other vulnerable lands, such as the Greater Moe’s Valley Area, and we urge decision-makers to join us in securing permanent protections for these invaluable spaces.”

Kya Marienfeld, Wildlands Attorney, Southern Utah Wilderness Alliance:

“Authorizing a major freeway through a Congressionally-designated conservation area should never have happened in the first place. This fight, just to uphold Congress’ intent to protect Red Cliffs for conservation, recreation, and wildlife, has dragged on unnecessarily for almost a decade, but we’re pleased the agencies still firmly recognize the value and importance of this gem of public lands and are recommitting to protecting the important habitat and cultural sites that a four-lane highway would have damaged forever.”

Charlotte Overby, Vice President of Conservation Field Programs, Conservation Lands Foundation

“This decision is a resounding victory for Red Cliffs National Conservation Area and for National Conservation Lands across the country. Allowing a highway to carve through a Congressionally designated conservation area would have set a dangerous precedent, undermining the very purpose of these protections. National Conservation Areas like Red Cliffs are established to preserve their unparalleled natural, cultural, and recreational values, and today’s decision reaffirms that these designations are permanent and must remain for future generations."

Vera Smith, Senior Federal Lands Policy Analyst, Defenders of Wildlife

“The Red Cliffs National Conservation Area is no place for a highway. This conservation area was created to protect stunning scenery and habitats for species like the Mojave desert tortoise that are fighting for survival in the face of expanding development and climate change. We are hopeful BLM’s denial of the highway application will mark the end of this ill-conceived idea forever.”

Lisa Belenky, Senior Counsel, Center for Biological Diversity

“The Bureau of Land Management is doing the right thing in rejecting a new highway through the stunning Red Cliffs National Conservation Area,” said Lisa Belenky, a senior counsel at the Center for Biological Diversity. “There are many alternative routes for traffic in the area but no other home for threatened desert tortoises, distinctive local plants and other wildlife. The conservation area also provides a natural refuge for people in this growing urban area. We’re committed to keeping it whole and wild.”

Chris Krupp, Public Lands Attorney, WildEarth Guardians

“It was shortsighted to propose a highway through the heart of a national conservation area, especially one that is so integral to the sense of place as Red Cliffs is. BLM made the right decision for desert tortoise—a species that, due to ongoing development of wild lands, continues to decline across much of its range. But it also made the right decision for the long-term future of Washington County residents.”

Jose Witt, Nevada State Director, The Wilderness Society

“We appreciate the careful and thorough analysis--yet again—of the ill-conceived proposal to build an unnecessary highway through the Red Cliffs National Conservation Area. The Red Cliffs NCA should continue to be managed for the purposes for which it was designated in 2009: to conserve, protect and enhance for the benefit and enjoyment of present and future generations the ecological, scenic, wildlife, recreational, cultural, historical, natural, educational and scientific resources of the National Conservation Area and to protect the endangered species that depend on it.”

A Decades-Long Community Fight for Red Cliffs

Since 2006, local residents and concerned citizens across the country have voiced opposition to the highway, pointing out transportation alternatives outside of Red Cliffs NCA that would do a better job of relieving traffic congestion, supporting economic growth and protecting wildlife, scenic beauty and local access to trails.



Despite immense local opposition to the proposed highway, the Bureau of Land Management and U.S. Fish and Wildlife Service approved a right-of-way for the Northern Corridor Highway in the final days of the first Trump Administration, prompting the local and national conservation organizations quoted above to file a lawsuit challenging the decision. The lawsuit argued that the highway violated multiple federal laws, including the Omnibus Public Land Management Act, Endangered Species Act, National Environmental Policy Act and others. A settlement agreement was reached in November 2023, ultimately paving the way for today's decision. Shortly after, a U.S. District Court remanded the 2021 approval of the right-of-way, confirming that the highway would fragment sensitive wildlife habitat for threatened species, reduce outdoor recreation access to the area and set a dangerous precedent for protected public lands across the U.S.

Background on Red Cliffs National Conservation Area (NCA):

The 44,724-acre Red Cliffs NCA is part of the larger Red Cliffs Desert Reserve that is collaboratively managed by the BLM, the FWS, the State of Utah, Washington County and other municipalities. The Reserve was established under the 1995 Habitat Conservation Plan (HCP) as part of a “grand compromise” to protect ~61,000 acres of public lands for the Mojave desert tortoise (listed as “threatened” under the Endangered Species Act), while opening 300,000 acres of state and private lands for development. The Red Cliffs National Conservation Area was established in 2009 by Congress to “conserve, protect, and enhance…ecological, scenic, wildlife, recreational, cultural, historical, natural, educational, and scientific resources” of the public lands within the unit.


The region is home to important populations of the threatened Mojave desert tortoise and other at-risk plants and animals including the Gila monster, burrowing owl and kit fox. The Mojave desert tortoise is on a path to extinction according to leading researchers and its habitat in Southwest Utah, which houses some of the densest tortoise populations, is especially vulnerable given recent and anticipated growth in the region. The NCA is 45 miles from Zion National Park, and includes 130 miles of trails, two wilderness areas, heritage public use sites, Native American cultural artifacts, several threatened/endangered species and one of Utah’s most popular state parks, Snow Canyon State Park. People from all over the state, country and world visit to hike, mountain bike, rock climb, horseback ride, photograph and marvel at the expansive red rock landscape.

This comprehensive Policy Handbook details the foundation and future vision for the National Conservation Lands
By Maria Gonzales December 10, 2025
Some of my earliest and most formative memories are on public lands in New Mexico, where I grew up camping under impossibly starry skies, hiking rocky canyons, and exploring every sunbaked arroyo in Santa Fe for lizards and other small critters. Growing up in the Southwest made me deeply aware of both the beauty and the fragility of these landscapes. I saw how fire, drought, and mismanagement could threaten not only ecosystems, but the health and well-being of the communities who depend on them. Those experiences shaped me. They taught me that caring for wild landscapes isn’t passive, it’s a collective responsibility. That belief has guided my career and approach to leadership: philanthropy is fundamentally about stewardship, community, and creating the conditions for impact to scale. It’s also what drew me to the Conservation Lands Foundation. Its clarity of mission, its commitment to community-led conservation, and its track record of protecting and expanding the National Conservation Lands represent the future of protecting nature, one rooted in collaboration, shared power, and long-term investment.

Washington, D.C. — The Senate Energy and Natural Resources Committee heard five conservation bills, which will enact much-needed new protections for public lands in Colorado, Nevada and New Mexico. Below is a statement from Chris Hill, CEO of the Conservation Lands Foundation, which represents a national network of community advocates who are solely focused on the public lands overseen by the Bureau of Land Management, including the National Conservation Lands: “We thank the champions in the Senate who introduced and continue to move forward these important bills that protect the public’s access to nature and essential wildlife habitats, while supporting Tribal culture and economies. It’s heartening to see the Senate advance meaningful public lands policy with the bipartisan support we know exists with their constituents. These bills include: S. 1005 Southern Nevada Economic Development and Conservation Act, sponsored by Senators Cortez Masto and Rosen of Nevada. S.764 Colorado Outdoor Recreation and Economy (CORE) Act, sponsored by Senators Bennet and Hickenlooper of Colorado. S. 1195 Pershing County Economic Development and Conservation Act, sponsored by Senator Rosen of Nevada. S. 1319 Pecos Watershed Withdrawal and S. 1476 M.H. Dutch Salmon Greater Gila Wild and Scenic River Act, both sponsored by Senators Heinrich and Luján of New Mexico. “These bills honor our collective commitments to strengthen our bonds with the lands we know and love and we urge the Senate Energy and Natural Resources Committee to ensure they are passed by the full Senate quickly.” ###

Washington — Six organizations sent a letter to the Acting Director of the Bureau of Land Management (BLM), warning that at least 5,033 oil and gas leases — covering nearly 4 million acres — may now be legally invalid. The letter asks the agency to halt all new leasing and permitting until it “ensure[s] compliance with the law and remed[ies] this grave legal uncertainty.” Ultimately, Congress must fix the legal crisis it created. The letter details how Congress' unprecedented use of the Congressional Review Act (CRA) to overturn BLM Resource Management Plans (RMPs) has called into question the legal efficacy of every land management plan finalized since 1996. These plans don't just guide management decisions; they enable everything that happens on public lands, from oil and gas drilling to recreation, grazing, and wildlife protection. If land use plans may now be invalid, then thousands of oil and gas leases and drilling permits issued under them may also be invalid Congress Was Warned About CRA Consequences When Republican members of Congress voted in October to use the CRA to overturn three RMPs in Alaska, Montana, and North Dakota, they ignored urgent warnings from conservationists, legal scholars, former BLM officials, and even some energy industry voices about the chaos this would unleash. The agency's own Solicitor’s Office cautioned that treating RMPs as “rules” could call into question the validity of every BLM plan since 1996 — along with the leases, grazing permits, rights-of-way, and other decisions based on those plans. Thirty leading law professors warned that this move could jeopardize “thousands of leases and management decisions across hundreds of millions of acres.” Former BLM leaders said overturning land-use plans under the CRA would “undermine the basis for authorizations” and create widespread legal uncertainty for energy developers, ranchers, and recreation permittees, threatening the integrity of the entire planning system. But Congress ignored these warnings — and is now moving ahead with even more CRA resolutions that will escalate the crisis. "By incorrectly treating land use plans as rules under the Congressional Review Act, Congress hasn't just overturned three plans — they've thrown every plan finalized since 1996, representing 166 million acres, into doubt. That mistake replaces a stable, science-based, community-driven system with needless chaos and uncertainty. It was lazy and irresponsible and is harmful to all land users," said Jocelyn Torres, chief conservation officer at the Conservation Lands Foundation. Along with the at least 5,033 existing leases, the legal uncertainty extends to future leasing. According to the letter, 69.8% of all BLM lands available for oil and gas leasing are managed under RMPs finalized after 1996 that were never submitted to Congress. BLM is currently evaluating 850 parcels totaling 787,927 acres across 14 upcoming lease sales on lands that may lack a valid RMP. This legal chaos affects far more than oil and gas. Land management plans for national forests, national parks, and national wildlife refuges finalized since 1996 may also be invalid, potentially calling into question grazing permits, timber sales, recreation authorizations, and wildfire management projects across hundreds of millions of acres nationwide. "Congress was warned repeatedly that weaponizing the CRA against land management plans would create exactly this kind of chaos. They charged ahead anyway, putting short-term political gain ahead of stable land management. Now they've jeopardized the very oil and gas development they claimed to be protecting. Congress must immediately fix the mess it made." said Alison Flint, senior legal director for The Wilderness Society . “Let’s be crystal clear: The Congressional Review Act is bad public policy. And it’s absolutely terrible public policy when used to overturn comprehensive public land planning decisions that radically reduces predictability for all public land users — in particular, as we have highlighted to the Bureau of Land Management, the oil and gas industry itself,” said Melissa Hornbein, senior attorney at the Western Environmental Law Center. “Congress lit the fuse on a legal time bomb that now calls into question the validity of thousands of oil and gas leases covering millions of acres as well as grazing permits and numerous other authorizations. But equally concerning, use of the CRA unravels decades of community-led land-use planning and throws into disarray the legal foundation for how our public lands are managed,” said Laird Lucas, executive director at Advocates for the West. “Congress’s use of the CRA to disapprove several Bureau of Land Management land use plans that were put in place following years of stakeholder and Tribal Nation input has sown confusion throughout the American West. This is not what Congress intended when it passed the CRA,” said Steve Bloch, legal director for the Southern Utah Wilderness Alliance. “As one of the principal architects of this newest line of attack on public lands, Sen. Daines opened Pandora’s Box. Using the Congressional Review Act to wipe out years of local work on Resource Management Plans is unprecedented, and it puts rural economies at risk, including the oil and gas industry. Inserting Congress into these processes threatens to unravel the foundations of public resource management and dismantle the systems that communities, businesses, and Montanans rely on. Congress is heading down a reckless path, yet another example of the pattern of attacks we’re seeing out of Washington D.C. on one of the most foundational aspects of Montana’s way of life: our public lands and resources,” said Aubrey Bertram, Staff Attorney & Federal Policy Director at Wild Montana.
Congress with text
November 19, 2025
Washington, D.C. — The U.S. House last night used the Congressional Review Act to consider and pass three resolutions undermining public lands protections in three areas in Alaska and Wyoming. The three resolutions are: S.J. Res. 80 – disapproving of the ‘‘National Petroleum Reserve in Alaska Integrated Activity Plan Record of Decision’’. H.J. Res. 130 – disapproving of the ‘‘Buffalo Field Office Record of Decision and Approved Resource Management Plan Amendment’’. H.J. Res. 131 – disapproving of the ‘‘Coastal Plain Oil and Gas Leasing Program Record of Decision’’. Below is a statement from Jocelyn Torres, Chief Conservation Officer of the Conservation Lands Foundation, which represents a national network of community advocates who are solely focused on the public lands overseen by the Bureau of Land Management (BLM), including the National Conservation Lands: “Today’s action by the U.S. House is part of a series of coordinated attempts to roll back common sense management of public lands. It’s simple - America’s public lands should be managed for the public good. These resolutions undermine the U.S. Bureau of Land Management’s authority to manage public lands for the benefit of all Americans, not just those who seek to buy up and close public lands to public access and benefit. “It is clear from the recent actions of this Congress to remove protections from key areas across the West that supporters of these actions are opponents of public lands. By removing the BLM’s authority to manage lands, these resolutions ensure that privatizing or industrializing them are the only viable remaining options. It’s a classic example of trying to solve a problem that was self-inflicted for the express purpose of achieving an outcome that benefits you. “We remain opposed to these one-sided, destructive attempts to roll back the clock on public lands protection and we’ll continue to work with members of the Friends Grassroots Network to oppose these obvious attempts to use public resources for private gain. We’ll continue to remind members of Congress that the overwhelming majority of Americans support responsible, effective, balanced management of the public lands.” ###
