General Description: Opened in May 2007, the Penobscot Narrows Bridge and Observatory is the only bridge observatory in the United States spanning 2,120 feet between the shores and 135 feet above the river. The Observatory is in the west pylon on the bridge extending 420 feet above the river. A minute elevator ride to the top provides 360 degree panoramic views of the river, bay, and Maine interior. Each pylon is made from local granite quarried at Mt. Waldo. This source of granite was also used for part of the Washington Monument and each pylon was designed to resemble the Washington Monument.
1) This is the most unique bridge I have ever seen. As you approach the bridge for the first time you are struck by its grandeur and the resemblance to the Washington Monument is obvious. I was surprised to find out it was only a two land bridge high above the Penobscot River.
2) As expected, the view from the top of the observatory is spectacular. They have a number of displays at the top pointing out the many features, both near and far, that you can see from the platform.
