The Penobscot Narrows Bridge is a 2120ft long cable-stayed bridge that carries US 1/SR 3 over the Penobscot River. It connects Verona Island to Prospect, in the U.S. state of Maine. It replaced the Waldo–Hancock Bridge, built in 1931.Technical informationThe Penobscot Narrows Bridge is one of three bridges in the US constructed recently to utilize a cradle system that carries the strands within the stays from bridge deck to bridge deck, as a continuous element, eliminating anchorages in the pylons. Each epoxy-coated steel strand is carried inside the cradle in a one-inch steel tube. Each strand acts independently, allowing for removal, inspection and replacement of individual strands. The cable-stay system was designed with a system that uses pressurized nitrogen gas to defend against corrosion.In June 2007, six reference strands within three stays were replaced with carbon fiber strands – a first in the US. Monitoring on the strands will evaluate this material for future use in bridge designs. These engineering innovations helped the bridge appear in the December 2006 edition of Popular Science as one of the 100 best innovations of the year. The total project cost was $85 million.

  • Just happen to come upon this attraction on the way to Bar Harbor. Fort Knox Historical Park and Bridge Observatory. Great Fort and great views from 400ft up. 
  • Tremendous views from the observation decks! Get tickets at Fort Knox, then ride the elevator 40+ stories up. Three levels of observation decks so it was not crowded when we visited near closing time....  read more »
  • Crossed this beautiful bridge on the way to Acadia and decided to check it out on the way back. You can buy a ticket and take an elevator to an observation deck at the top for 360 views. I would recommend taking a trip up to the top in the Fall for fantastic foliage views. For photogs, it's completely glass cased at the top so watch out for glare.
  • Definitely a great place to stop! Don't just see the bridge visit Fort Knox also!
  • The Bridge is a marvel of construction. The granite used in the towers was came from the same quarry that supplied granite used on the Washington Monument.
  • Spectacular view and an affordable combo ticket for the observatory and the fort.
  • This was a fun pit stop. Cost $7 per adult to take the elevator to the observation deck to the top. There was a storm coming in when we were up there so it was beautiful and thrilling all at the same time.
