The Sterling Highway is a 142-mile (229-km) highway in the Southcentral region of the U.S. state of Alaska, leading from the Seward Highway at Tern Lake Junction, 90 miles (140 km) south of Anchorage, to Homer.
Construction of the highway began in 1947 and was completed in 1950. It is part of Alaska Route 1. It leads mainly west from Tern Lake to Soldotna, paralleling the Kenai River, at which point it turns south to follow the eastern shore of Cook Inlet. It is the only highway in the western and central Kenai Peninsula, and most of the population of the Kenai Peninsula Borough lives near it. The highway also gives access to many extremely popular fishing and recreation areas, including the Kenai, Funny, and Russian rivers.
Mileposts along the Sterling Highway do not begin with 0 (zero). Instead, they begin with Mile 37 (km 59), continuing the milepost numbering of the Seward Highway where the two highways intersect near Tern Lake. The 0 (zero) mile marker for the Seward Highway is at its terminus in downtown Seward at the intersection of 3rd Avenue and Railway Avenue. Thus, mileposts along the Sterling Highway reflect distance from Seward, which is not actually on the Sterling Highway.
