According to Alaska's supplement to the Federal Manual on Uniform Traffic Control Devices, AK-7 follows (from south to north):[2] No other segments are shown on maps.

The southernmost piece of AK-7 is known as the Tongass Highway and heads both ways from Ketchikan on Revillagigedo Island.

Continuing downtown it is successively Water, Front, Mill and Stedman streets, becoming the Tongass Highway again after passing Coast Guard Base Ketchikan.

AK-7 also includes the short Nordic Drive, connecting the Mitkoff Highway to the north point of the island.

There were plans to extend the road north of Berners Bay as the Lynn Canal Highway; however, the project has been indefinitely shelved due to the state's budget crisis.
