Сеуэрдское шоссе на Аляске: от Сьюарда до Анкориджа.

State highway in Alaska, United States
the section of Alaska Route 1 between Tern Lake Junction and Anchorage

The Seward Highway begins at an intersection with Railway Avenue, in Seward, less than 300 feet (91 m) from Resurrection Bay. At this point, the Seward Highway is two lanes, with a parking lane on each side. The Seward Highway is designated as AK 9 at this point of the route. The highway continues through downtown Seward and residential areas. The highway continues past the Seward Airport and Exit Glacier road, before entering the unincorporated community of Bear Creek. Just after entering Bear Creek, a series of tracks belonging to the Alaska Railroad comes alongside the roadway. These railroad tracks continue on with the Seward Highway until Moose Pass, return near a junction with the Portage Glacier Highway, and remain until the highway becomes a freeway, in southern Anchorage. The Seward Highway proceeds through central Bear Creek, passing Bear Lake, until entering Chugach National Forest.

The Seward Highway enters the Chugach National Forest just after its start. The highway enters the Chugach National Forest while it is still part of the Bear Creek community, so it gives the appearance of still being inside that census designated place. After a mile or so (1.6 km) though, the area surrounding the highway begins to look more like a national forest. The Alaska Railroad weaves back and forth under the highway, which causes the highway to traverse a series of small bridges. For a few miles after the bridges, the Seward Highway is a four lane road, but then merges back to two lane. After passing through about 10 mile (16 km) of forest, the highway passes Primrose Spur Road, and enters Primrose. For the next five or so miles (8 km), the route runs on a thin strip of land between the mountains and Kenai Lake. At the northern end of Kenai Lake, the route passes through Crown Point, and provides access to a large campground where Trail Creek empties into Kenai Lake. The highway runs alongside Trail Creek for about , before passing the settlement of Moose Pass. The road continues, passing along Upper Trail Lake for a few miles, before returning to the dense forest, and passing a large mountain range. After a few more miles, the road passes the Tern Lake Junction, and intersects with Alaska Route 1 (AK 1) (also known as the Sterling Highway), where Alaska Route 9 terminates, and the Seward Highway is designated to AK 1. It is at this point that the road begins to climb into the actual mountains to approach Turnagain Pass. For several miles, the roadway continues through large, Alaskan spruce forests. After approximately , the highway passes Summit Lake, and provides access to another large campground. The road then continues through the mountains. After about , the route intersects the Hope Highway, which provides access to the city of Hope, and the highway reenters forest. The route continues through the mountains for about more, before a steep decline, at which point the highway exits the Kenai Peninsula and continues along the shores Turnagain Arm. Just after reaching Turnagain Arm, the highway enters the city limits of Anchorage (and remains within Anchorage proper for the remainder of its route). After intersecting the Portage Glacier Highway the Alaska Railroad tracks again come alongside the route. The highway continues through the Chugach National Forest for approximately , passing the Turnagain Arm to the west, and the Kenai Mountains to the east. It then exits the Chugach National Forest, having spent approximately inside its boundaries. AK 1 continues on for a short period as 5th Avenue, before becoming known as the Glenn Highway.

An 18 mile (29 km) stretch of the Seward Highway, traveling from Seward to Kenai Lake was completed in 1923. Another segment of the highway, running between Moose Pass and Hope, was completed in 1928. The Mile 18 bridge, nicknamed "The Missing Link", which would connect the Seward and Moose Pass portions, was not completed until 1946, which was a major cause of the delayed completion of the highway. connecting Seward to the major city of Anchorage by road for the first time (Seward was previously reached by sea, rail, or air). The entire length of the highway was paved in 1952. The length of the highway traveling from the AK 1 and AK 9 intersection to the northern terminus is designated as Interstate A 3 by the National Highway System. In 2017, Alaska DOT&PF announced a four year Milepost 75–90 Rehabilitation Project, scheduled to begin in 2018, to make major safety improvements to a busy crash prone section of the Seward Highway from Girdwood to beyond the Portage curve toward Turnagain Pass ending at Ingram Creek. In July 2015 a tour bus crash at milepost 79 killed one man and critically injured several others, causing a 10 hour traffic jam. During the summer months, up to 15,000 vehicles use this 15 mile (24 km) stretch of Seward Highway daily.

Seward Highway is part of the unsigned part of the Interstate Highway System as Interstate A 3.

United States Bicycle Route 97 is a U. S. Bicycle Route located along Alaska Route 1. The bike route runs alongside the Seward Highway along the entire length of the highway. The bike route was created in 2011.
