Ambler Road Project

NPS/Ken Hill The Alaska National Interest Lands Conservation Act (ANILCA) authorizes access for an industrial mining road through a portion of Gates of the Arctic National Preserve. Section 201(4)(b) states that "Congress finds that there is a need for access for surface transportation purposes across the Western (Kobuk River) unit of Gates of the Arctic National Preserve...and the Secretary shall permit such access in accordance with the provisions of this subsection." On June 30, 2016, the Alaska Industrial Development and Export Authority (AIDEA) submitted a final revised application for the Ambler Mining District Industrial Access Project. The proposal is for the construction and operation of a 211 mile all-season controlled-access industrial road connecting the Ambler Mining District with the Dalton Highway. Approximately 26 miles of the proposed road crosses NPS lands. On October 6, 2025, President Trump directed his Administration to promptly issue authorizations necessary for the establishment of the 211 mile Ambler Road Project. The Gates of the Arctic National Park and Preserve Right of Way Permit for the Ambler Road was issued on October 21, 2025.
