U.S. 1A

There are several U.S. 1A's within the state of Maine. One of the most significant ones is the loop northward from U.S. 1 at Stockton Springs to Bangor-Brewer and back to U.S. 1 at Ellsworth. This loop provides part of the main routing to coastal Maine, including the popular Bar Harbor and Acadia National Park areas, from Maine's Interstate system.

U.S. 1A east combines with Maine 9 east at Western Avenue in Hampden. The tandem continue north to Bangor while Maine 9 west merges with U.S. 202 nearby to Unity.
