Parks Highway Fish Passage Improvement Plan

Cover image of the Parks AOP Grant Application

The Alaska Department of Transportation and Public Facilities (DOT&PF), through the assistance of the Alaska Department of Fish & Game (ADF&G) proposes using a grant from the National Culvert Removal, Replacement and Restoration Grant Program (Culvert Aquatic Organism Passage Program) to replace up to 12 deficient culverts on the Parks Highway as part of a larger drainage and fish passage culvert improvement plan. The project area is between Mile Post 99 north of Anchorage to MP 163 outside the Denali National Park and Preserve (DNP&P).

Depending on funding, the FHWA AOP Culvert Grant Request would replace three culvert sites with bridges and would replace the remaining nine sites with appropriate fish passage structures. The completed project would open 51.5 miles of barrier free upstream anadromous habitat and nearly 420 acres of lake habitat.
