Seward Highway is in south-central Alaska on the Cook Inlet. The byway begins in the city of Anchorage and travels south through the Chugach National Forest to the community of Seward. The scenic drive follows AK 1 and AK 9, which are two-lane paved roads. The roads are suitable for all types of vehicles although some sections are narrow and winding. Seward Highway is 127 miles long and is usually open year-round. Winter driving conditions may be hazardous. Snow avalanches can temporarily close sections of the highway.
