Day 28: Fort Knox and Penobscot Narrows Bridge and Observatory

Beautiful fall weather again today, with clear skies and temperatures in the 70s. I reluctantly left Eden and took Highway 1 south. My main goal was to visit Fort Knox State Historic Site near the town of Bucksport, especially the observatory there. I love high viewpoints, since they are the best way to see the lay of the land.

Penobscot Narrows Bridge spans the Penobscot River, Maine's longest river. The bridge opened in 2007, replacing an older bridge that was in disrepair. The bridge observatory is 42 stories (420 feet) above the river, and is the tallest bridge observatory in the world and also the tallest occupied structure in the state of Maine. A quick elevator ride up and then a short walk up two more flights of stairs is rewarded with impressive views of Penobscot River and Bay and the surrounding hills and low mountains.

I expected that to be the highlight of my day, but I was simply amazed at the architecture and engineering of Fort Knox, named after Henry Knox, the first U.S. Secretary of War (the other, more well-know Fort Knox in Kentucky is also named after him). I spent just over half an hour at the observatory, but over two hours at the fort exploring its tunnels, cannons, and overall layout. The fort was built to repel British attacks on the area. During the American Revolution and the War of 1812, British ships sailed up the Penobscot River, seizing control of the river and surrounding areas. To prevent this from happening again, according to a brochure from the park, in 1844 the U.S. Department of War and its Corps of Engineers began building Fort Knox, which was situated to be able to guard the narrow channel through which all ships had to pass when traveling upriver. (Geographers call this a choke point, which is a strategic area such as a mountain pass or narrow waterway that can be easily defended.) Construction continued for 25 years. Troops were only stationed there twice (briefly), during the Civil War and the Spanish-American War. The 74 cannons never had to be used, though, since no enemy ships ever came up the river.

I traveled a total of 135 slow miles on Highway 1 through various small and scenic coastal towns that were bustling with Sunday afternoon tourists and traffic. I've now logged 4,514 miles on this journey.
