Edgerton Highway

Edgerton Highway is a 33-mile paved road in southcentral Alaska that connects the Glenn Highway near Copper Center to the vicinity of Chitina and provides access to Wrangell–St. Elias National Park, Valdez, and interior trail systems. The highway follows the Copper River valley and serves as an important spur for tourism, resource access, and local communities such as Kenny Lake and Chitina. It is maintained by the Alaska Department of Transportation and Public Facilities and is part of a network linking the Alaska Highway corridor with coastal and interior Alaska destinations.

Route description

The highway begins at a junction with the Glenn Highway near Copper Center and proceeds northward, paralleling the Copper River and following historic routes used by the Copper River and Northwestern Railway and prospectors tied to the Klondike Gold Rush. It crosses low-angle alluvial flats and braided streams before entering forested slopes dominated by stands of Sitka spruce and white spruce typical of Alaska Range foothills. Key waypoints along the route include the communities of Chitina, Kenny Lake, and access roads to McCarthy and the Kennicott Glacier area of Wrangell–St. Elias National Park. The road surface is paved for most of its length, with pullouts near viewpoints overlooking the Nabesna Glacier drainage and the confluence of tributaries that feed the Copper River. At its northern terminus travelers encounter access to the McCarthy Road and dirt spurs toward remote salmon streams used by Alaska Native fish camps and commercial fishing operations near Chitina River.

History

Construction of the route dates to the 1940s when state and territorial authorities sought to improve connections between Valdez port facilities and interior mining districts, building on trails used during the Alaska Gold Rush era and earlier indigenous pathways used by Ahtna peoples. The alignment took advantage of grade corridors previously developed by the Copper River and Northwestern Railway constructed for the Kennecott Copper Corporation to serve the Kennicott copper mine near McCarthy. During the mid-20th century the Alaska Road Commission and later the Alaska Department of Transportation and Public Facilities upgraded segments for vehicle traffic, responding to growth in tourism promoted by National Park Service designations and increased commercial access to Prince William Sound. The road played roles in regional mobilization during World War II logistics planning and in supply routes for mining and fishing industries regulated under laws such as the Alaska Native Claims Settlement Act era developments. Periodic improvements addressed flooding from the Copper River and permafrost-related issues documented by US Geological Survey studies.

Major intersections

- Junction with Glenn Highway near Copper Center — southern terminus, primary link to Anchorage and Fairbanks via the Alaska Highway system. - Access road to Kenny Lake community and Kenny Lake Airport — local connector for residents and seasonal workers. - Turnoffs for McCarthy and Kennicott Glacier via the McCarthy Road spur — gateway to historic Kennicott and Wrangell Mountains. - Access to Chitina and the Chitina River crossings — northern terminus region where highways transition to local roads and seasonal ferry or trailheads. These intersections link the highway to broader corridors including Valdez–Cordova access routes and trails leading into Wrangell–St. Elias backcountry.

Traffic and usage

Traffic on the highway is a mix of local commuter flows, commercial freight servicing mining and timber operations, recreational vehicles, and seasonal visitor surges tied to NPS tourism, fishing seasons, and winter access to snowmobile trails. Annual Average Daily Traffic (AADT) varies significantly, with higher counts during the summer months as travelers arrive from Anchorage and Valdez; winter usage includes utility and maintenance vehicles accessing remote installations supported by the State of Alaska and private operators. The route is occasionally subject to closures or restrictions due to spring breakup, river flooding, avalanche hazards in feeder valleys, and maintenance work coordinated with the Federal Highway Administration and state agencies. Emergency services coordinate with Alaska State Troopers and local search-and-rescue teams from communities such as Chitina.

Scenic and recreational features

The highway provides panoramic vistas of the Wrangell Mountains, Nabesna Glacier, and the historic Kennicott Glacier region, attracting hikers, photographers, and backcountry enthusiasts linked to National Park Service programs. Trailheads accessible from the road lead into valleys used for alpine climbing popular with visitors to peaks like Mount Blackburn and Mount Sanford, and rivers along the corridor support salmon runs that draw sport anglers and commercial fleets associated with the Alaska Department of Fish and Game. Wildlife viewing opportunities include sightings of brown bear, moose, and migratory birds protected under statutes enforced by the US Fish and Wildlife Service. Visitor amenities and interpretive sites highlight indigenous Ahtna cultural heritage, the history of the Kennecott mining district, and conservation narratives promoted by organizations such as the National Park Service and local historical societies.
