This is why the road was built, to first construct, then maintain the 800-mile Alaska Pipeline from Prudhoe Bay to Valdez, Alaska, where the oil is transferred to oil tankers. The oil is heated to thin it as it moves between the pumping stations along the way. This is one of a few places where it is legal to stand near the pipe. It is really a metal pipe, surrounded by insulation, then an outer covering, but if you put your hand on the outer shell you can actually feel the warmth from the heated oil inside.
