This is one of the largest pipeline systems in the world and the only way to get crude oil from Alaska's North Slope fields to tankers waiting in Valdez. For update, click here.
Built in the 1970s after oil was discovered at Prudhoe Bay (1968), the 48-inch diameter, 800-mile pipeline links Prudhoe Bay on the Arctic Ocean with the terminal at Valdez, the northernmost ice-free port in the Western Hemisphere. The flow from this pipeline accounts for roughly 20 percent of U.S. oil production annually.
