Which Alaskan highway is known as the "Haul Road" and goes to the Arctic Ocean?

The Alaskan highway known as the “Haul Road” and reaching the Arctic Ocean region is the Dalton Highway, officially Alaska Route 11. It runs north from the Elliott Highway near Livengood to Deadhorse near Prudhoe Bay, paralleling much of the Trans-Alaska Pipeline System.

The road was built to support North Slope oil development and pipeline construction. A major construction effort in 1974 rapidly extended the route northward, and the state later named it the James W. Dalton Highway after an Alaskan engineer and oil-exploration consultant. The highway was opened to the public in stages; full public access was allowed in 1994.

The description “goes to the Arctic Ocean” is shorthand rather than a claim that the highway ends on an ocean beach. Dalton Highway ends at Deadhorse, an industrial settlement near Prudhoe Bay and the Arctic Ocean. Public travellers generally need to arrange or use local access to continue toward the coast, depending on current restrictions.

The Dalton is famous for its isolation and harsh conditions. It is about 414 miles long, crosses the Brooks Range at Atigun Pass, and remains partly gravel. The Taylor, Glenn, and Seward highways are important Alaskan roads, but none is the North Slope supply route identified as the Haul Road.
