Nikiski Alaska Pipeline (purple)

The Nikiski Alaska Pipeline was constructed in 1976. The pipeline has a 10.75-inch outside diameter and transports refined petroleum products (jet fuel, gasoline and diesel) from Tesoro’s Kenai Refinery to the Port of Anchorage. Nikiski Alaska Pipeline is a buried pipeline that begins at Tesoro Alaska Pipeline Company’s (Tesoro) Kenai Refinery in Nikiski. The pipeline route runs along the Kenai Spur Highway through the Captain Cook State Recreation Area, and then parallels the coast to Point Possession before crossing the Turnagain Arm. The pipeline route continues along the Tony Knowles Coastal Trail, through the Ted Stevens Anchorage International Airport, and then along Northern Lights Boulevard. The pipeline runs near the Alaska Railroad right-of-way for the remainder of the route, terminating at the Port of Anchorage.
