Glenn Highway, National Scenic Byway in Alaska, United States
The Glenn Highway is a 189-mile road stretching from Anchorage to Glennallen across south-central Alaska. It follows the Matanuska River as it passes through mountains and valleys, connecting communities along the way and offering access to Matanuska Glacier.
The highway was built in 1945 to create the first road link between Anchorage and the Richardson Highway. This connection played a key role in Alaska's post-war development by improving transportation between distant communities.
The route crosses lands of the Ahtna and Dena'ina peoples, who have lived here for generations and continue to maintain their connection to the area. Information centers along the way share how these communities have used and understood this landscape for centuries.
The highway is passable for most of the year and links several communities along its route. Conditions vary with the seasons, so travelers should check weather updates and road status before setting out, especially during winter months.
Near mile marker 102, travelers can reach Matanuska Glacier directly and walk on the ice formations year-round. This access point makes it unusually easy to experience ancient ice without special equipment or climbing skills.
