Alaska’s Brooks Range is sometimes called the most Alaskan part of Alaska, and for good reason. The arctic mountains and valleys, stretching 700 miles from the Yukon border to the Chukchi Sea, offer a step back in time. There, you can witness massive caribou migrations and pursue everything from sheefish to Dall sheep, grizzly bear to Dolly Varden. The Brooks is the sort of place that supports a subsistence lifestyle as well as unparalleled outdoor opportunities for visiting hunters, anglers, and anyone who loves America’s wild public lands. The proposed Ambler Industrial Road threatens all that.
If built, the private road would stretch 211 miles across the southern foothills of the Brooks Range and serve to develop some 1,700 mining claims. The companies that own these mines have made it clear that their intention is to ship the ore to Asia, specifically China. By enabling raw minerals to be exported overseas, the Ambler Road project would deepen U.S. dependence on foreign mineral processing and supply chains. This would directly undermine America First priorities which emphasize reducing reliance on adversarial nations for critical minerals and strengthening American control over strategic critical resources.
Now, let’s discuss how the project is likely a multi-billion-dollar boondoggle for American taxpayers.
AIDEA and Rising Estimates
The Ambler Road is backed by Alaska’s state-owned and financed corporation, the Alaska Industrial Development and Export Authority. AIDEA is tasked with promoting economic development by financing businesses and industrial projects.
However, their track record is less than stellar, with reports from independent economists indicating AIDEA’s past decisions have lost the state $10 billion in opportunity cost. This is money that could have been used to fund schools, law enforcement, the Permanent Dividend Fund, social services, and any other state-funded entity. Over the last 35 years, AIDEA has left a trail of failed, abandoned, and money-losing projects in its wake, including the Mustang Road on the north slope of the Brooks Range and a fish processing plant in Anchorage. A bill was introduced in the 2025-2026 Alaska State Legislature, commonly known as the AIDEA Accountability Act, to increase oversight, transparency, and accountability of the entity, although it failed to pass this session. Now, a new report shows that the proposed Ambler Road could be another gamble made by AIDEA that could leave the bill with Alaskans.

The project will likely cost significantly more than estimated in 2024. The study puts the new cost at about $765 million for road construction; about $88 million for closure and reclamation; more than $630 million in long-term maintenance; and roughly $550 million in financing costs. Together, these figures bring the price tag to approximately $2.03 billion.
However, while this report’s construction and maintenance cost estimates represent updated, inflation-adjusted values, they do not address the potential deficiencies in the 2024 supplemental environmental impact statement’s original cost estimates. The proposed Ambler Road’s current estimated cost per mile is about $3.6 million. This estimate is notably lower than two other proposed remote road projects in the state: the Western Alaska Access Road and the West Susitna Access Road. The estimate for the Western Alaska Access Road is $5.6 million per mile. The estimate for the West Susitna Access Road is more than $10 million per mile. If construction costs for the Ambler Road ultimately track closer to estimates of the other two projects, a comparative analysis shows the estimated construction of the Ambler Road rising from $765.2 million to $2.17 billion, not including maintenance and financing.
This would mean the Ambler Road would cost American taxpayers closer to $3.5 billion over its lifetime with maintenance costs. Alaska is projected to receive roughly $1.1 billion in revenues from the project in mining license tax revenues, corporate income taxes, production royalties, and claim rents—less than a third of the costs.
Costs Are Still Evolving
AIDEA has described the construction estimate for the proposed Ambler Road as preliminary as it was developed before the final engineering design. At this stage, key factors including detailed road design, material sourcing, and construction logistics are still being drafted.
Infrastructure costs in remote regions of Alaska often rise as projects move from concept to construction, so the actual price is likely to increase. Environmental factors like floods and melting permafrost present additional challenges. Unknown maintenance costs following closure and reclamation of the road; yet-to-be-collected fisheries data that’s needed to design the road’s culverts and bridges; and inflation will also likely increase costs.
Additionally, AIDEA must pay for access across two Alaska Native Corporation lands. Those two corporations, Doyon and NANA, would charge for the road right of way across their lands.

The Revenue Question
AIDEA has proposed funding the construction of the proposed Ambler Road through revenue bonds. Under this model, upfront costs would be covered by the State of Alaska, with the expectation that tolls paid by future mining operations will repay the debt over time. This financial model depends on a future scenario where mining operations are developed and generate enough traffic to repay the bonds. This outcome is not guaranteed.
Mining projects in the Ambler district are still in early stages, and timelines for development can shift based on market conditions, permitting, and global demand. Without sufficient toll revenue, the obligation to repay the bonds remains. This raises a fundamental question: What happens if the expected revenue doesn’t materialize?
Unlike public highways that serve communities across Alaska, the Ambler Road is designed as a private industrial access road tied to future resource development. That distinction matters. It means the project’s financial success depends on a specific set of outcomes that are not promised.
A Decision with Long-Term Consequences
Hunters & Anglers for the Brooks Range treasures the Brooks as an intricate part of our American outdoor heritage and supports responsible development in Alaska. The Ambler Road is not responsible development.
Beyond negatively impacting world-class hunting, fishing, and other outdoor opportunities, the Ambler Road is a major outlay of taxpayer dollars with long-term consequences for Alaska. Alaskans and fellow Americans deserve a clear understanding of what this road could cost, and who carries the risk of funding this project.
The significant economic questions surrounding this project are one more reason that we believe the Ambler Road is a gamble not worth making.
