Project Overview x

HDL assisted the Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration with an Environmental Assessment for the extension of Anton Larsen Bay Road. The project was developed in cooperation with the Native Village of Ouzinkie and proposed to extend the road approximately two miles to a new road and boat launch and float/docking facility at the mouth of Anton Larsen Bay.

There is no road connection between the City of Kodiak and the outlying communities of Ouzinkie and Port Lions. Transportation options available to travelers between these communities include the Alaska Marine Highway System (AMHS), commercial and general aviation, and commercial and private boats.

Residents view travel via skiffs through the bay and vehicles on the road as the most cost-effective, convenient, and safe option for non-emergencies. During the spring, summer, and fall, travel from Ouzinkie or Port Lions to Kodiak via this route involves a roughly 30-minute skiff ride from either community to the Anton Larsen Bay Dock located near the head of the Anton Larsen Bay. From the dock, it is a 20- to 30-minute car ride via Anton Larsen Bay Road to the Kodiak Airport or the City of Kodiak.

In the winter, however, the interior portion of Anton Larsen Bay freezes over due to freshwater entering the head of the bay, preventing boats from launching from the dock or entering. During this time, marine travel is limited to a route around Spruce Cape along the northeastern tip of Kodiak Island. Northeasterly wind and ocean currents from the Gulf of Alaska often present difficult or dangerous travel conditions along the northeast of Kodiak Island’s shoreline.

Because the mouth of the bay receives less freshwater than the inland portion, the mouth freezes less frequently, increasing access to/from remote areas by boat in the winter. The extension project has been discussed locally since the 1960s and was recently included in the Kodiak Island Borough Capital Improvement Program.
