Penobscot Narrows Bridge, Prospect

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.

  • This bridge is super-cool. A new replacement for an older bridge that has since been removed, the exhibits on the grounds tell the story of the old bridge and the new, and there are remnants of the old bridge to see parts of the engineering of the time. Then the finale -- go up in the tower of the bridge (one of only a few in the world where you can do this) -- a fantastic view, even on a rainy day, of both the bridge and the way it is built, as well as the beautiful surrounding area and river. If you're in the area, you'd be crazy not to stop by.
  • Not long to drive across but a great place to visit. Views from the top are amazing. Wheelchair accessible.
  • I love this bridge it was a great idea to make a reality and im glad that the people decided to fund the building for it
  • Absolutely, almost unnecessarily beautiful bridge to top off whatever amazing adventure you were conducting here.
  • Incredible attraction. The observatory is one of a kind in the United States. Truly spectacular.
