History

1A has been around for several decades. In 2007, when US 1 was rerouted along I-295 through Portland, 1A was extended along the Fore River Parkway (a limited-access but low-speed connector opened in 2005) between its former junction with US 1 at the north end of the Veterans Bridge; to I-295 near the Congress Street interchange - never mind the fact that there's no direct connection between 1A south and 295 south there.

Guide

1A is a short connector to downtown Portland, particularly the Old Port district and the waterfront. Most of the route is along roads with limited on-street development.
