AAA Editor Notes
Penobscot Narrows Bridge & Observatory is at 740 Fort Knox Rd. To reach the observatory, visitors must enter Fort Knox State Historic Site.

Perched 420 feet atop the south obelisk of the 2,120-foot-long Penobscot Narrows Bridge, the observatory offers a panoramic view encompassing adjacent Fort Knox, the town of Bucksport, the Penobscot River and Penobscot Bay and the surrounding, heavily forested hills and coastal islands of “Down East” Maine. Visitors enter the base of the tower at the river’s edge and board an elevator that ascends to the three-floor, glass-walled observation area.

The high-tech bridge is a marvel of modern engineering, incorporating such innovative features as test cables made of a carbon composite material and cable sheaths filled with pressurized nitrogen to prevent corrosion.

Admission is by timed ticket.

(includes Fort Knox State Historic Site) $8; $5 (ages 65+); $4 (ages 5-11).
Daily 9-6, July-Aug.; 9-5, May-June and Sept.-Oct. Allow 30 minutes minimum.
