Polychrome Area Improvements: Design Changes

Denali National Park and Preserve » Polychrome Area Improvements: Design Changes » Document List

Since late August 2021, a portion of the Denali Park Road near Polychrome has been displaced by the Pretty Rocks Landslide (mile 45.4), cutting off vehicular access to popular visitor destinations and facilities including Polychrome Overlook, Toklat, Eielson Visitor Center, Wonder Lake, and Kantishna. The National Park Service completed an Environmental Assessment (EA) for improvements to the Park Road in the Polychrome Area to address several geologic hazards that are jeopardizing public safety and infrastructure. The Finding of No Significant Impact (FONSI) selected the alternative which includes constructing a bridge spanning the Pretty Rocks landslide and is expected to take three to four years to complete. As the bridge design progressed following the completion of the EA, some changes to the project have occurred.
