Arcola High Bridge; Arcola, MN
The Arcola High Bridge, or Soo Line High Bridge, is the most spectacular railroad structure in the area, and even with saturation foaming the Twin Cities for the last couple of years, this was my first time even seeing it in person. Low train volume and relatively difficult access result in very few photos.
Completed in 1911, the rail's nearly 200 feet above the water, with a total length of roughly 2,700 feet. John Weeks has an excellent page with more information:
Big tip of the hat to Rod Peters, my new best friend, for the super helpful updates on this train's location. The shot wouldn't have happened without him.
