The Penobscot River Bridge was a truss bridge between Bangor and Brewer, Maine. It was constructed by the American Bridge Company in 1902, with further construction in 1911 by the Boston Bridge Works. According to the Historic American Engineering Record, it was the last remaining Baltimore (Petit) through-truss bridge in Maine.

}} While it was designed for loads of up to 15 tons, it was reduced to 3 tons shortly before its replacement in 1997 by the "New Penobscot Bridge."{{Structurae|id=20017475|title=New Penobscot Bridge (1997)}}. Retrieved on 2007-07-16.

The bridge carried U.S. Route 1A and Route 15 across the Penobscot River. While 1A still crosses the New Penobscot Bridge, SR-15 was redirected over I-395's Veterans Remembrance Bridge after its completion in 1986.
