Penobscot Narrows Bridge and Observatory

The Penobscot Narrows Bridge extends 2,120 feet across the Penobscot River, connecting Verona Island to the mainland with its 447-foot-tall towers.

The structure replaced the 1931 Waldo-Hancock Bridge in December 2006, marking a new era for transportation infrastructure in coastal Maine.

Engineers integrated carbon fiber strands into the bridge design in 2007, establishing it as the first construction in the United States to use this material.

The observatory operates from May through October, sharing its schedule with Fort Knox State Historic Site and offering elevator access to the viewing platform.

At the top of the west tower, visitors reach the highest public bridge observatory worldwide, providing 360-degree views of the Penobscot River and mountains.
