Seward Highway
The Seward Highway is a highway in the U.S. state of Alaska that extends from Seward to Anchorage. It was completed in 1951 and runs through the scenic Kenai Peninsula, Chugach National Forest, Turnagain Arm, and Kenai Mountains. The Seward Highway is numbered Alaska Route 9 (AK-9) for the first from Seward to the Sterling Highway and AK-1 for the remaining distance to Anchorage. At the junction with the Sterling Highway, AK-1 turns west towards Sterling and Homer. About of the Seward Highway leading into Anchorage is built to freeway standards. In Anchorage, the Seward Highway terminates at an intersection with 5th Avenue, which AK-1 is routed to, and which then leads to the Glenn Highway freeway.
==Route description==
The full length of the Seward Highway has been listed on the National Highway System (NHS), a network of roads important to the country's economy, defense, and mobility. The segment designated AK-9 between Seward and Tern Lake Junction is part of the STRAHNET subsystem,〔 highways that are important to defense policy and which provide defense access, continuity and emergency capabilities for defense purposes.〔 The remainder that follows AK-1 is also designated Interstate A-1 (A-1) and included in the NHS on that basis.〔 The state's Interstate Highways are not required to comply with Interstate Highway standards, instead "shall be designed in accordance with such geometric and construction standards as are adequate for current and probable future traffic demands and the needs of the locality of the highway" under federal law. The highway is maintained by the Alaska Department of Transportation & Public Facilities (Alaska DOT&PF), and the A-1 designation is not signed along the highway. In 2010, 2,520 vehicles used the highway near the junction with Sterling Highway in a measure of the annual average daily traffic, the lowest tally along the highway. The highest traffic count as recorded by Alaska DOT&PF was 58,799 vehicles daily at the Dowling Road overpass in Anchorage. In 2012, Life magazine included the Seward Highway in its list of Most Scenic Drives in the World.
