The Dalton Highway reopened to traffic Friday morning as planned, following an 18-day closure caused spring breakup flooding from the Sagavanirktok River.
The highway, the main supply route for North Slope oil fields, opened to two-way traffic at 8 a.m., the Alaska Department of Transportation and Public Facilities said in a release.
Drivers can expect flaggers and a pilot car from Mile 412 to 414, and rough road conditions through the flood zone, from mile 392 through mile 414.
DOT said they expect costs for the emergency response to total $15.5 million.
