Governor Michael Dunleavy has signed a State Disaster Declaration following significant flooding damage along the Dalton Highway corridor, between Mileposts 315 and 404. This declaration enables emergency response measures and releases resources for permanent repairs on this critical supply route to Alaska’s North Slope.
The rapid spring melt in the Sagavanirktok River drainage area led to multiple sections of the highway being flooded and severed on June 14. The closure affected freight carriers, disrupted fuel and industrial equipment deliveries, and posed risks to petroleum operations and public safety. The North Slope is vital for oil production, which contributes nearly half of Alaska’s unrestricted revenue.
Efforts by DOT&PF crews and contractors are ongoing to restore the damaged 88-mile section of the highway. However, the extent of damage surpasses routine emergency maintenance capabilities.
“The Dalton Highway is an economic lifeline for Alaska — it keeps the North Slope energy sector supplied, supporting oil production that provides nearly half of the state’s unrestricted revenue,” stated a representative from Governor Dunleavy’s office. “The Governor’s swift action ensures we have the tools and flexibility to respond quickly, protect this vital corridor, and restore reliable access for industry.”
Coordination with federal agencies, emergency managers, and stakeholders will continue as part of recovery efforts. Updates on travel advisories for Dalton Highway can be accessed at 511.alaska.gov.
The Alaska Department of Transportation and Public Facilities manages numerous transportation infrastructures across the state including airports, ferries serving various communities, highways, and public facilities. Their mission is to “Keep Alaska Moving through service and infrastructure.”
