This bridge has very unique construction. It is made entirely of cut limestone, and set at an angle to the river. The whole bridge is built diagonally so that the center column runs parallel to the river. If you look close at the photo, you can see that all the courses of stone are offset about 8" to the one next to it. It's still in very good condition, considering that it's 100 years old. The railroad line discontinued traffic many years ago.
