Here’s about one-fourth of those huge wheels that raise and lower those even huger bridge lifts, from the 2013 trip down the industrial Calumet River sponsored by a local historical group. Most of the photos we’ve seen before of these have been from a distance, or otherwise hard to grasp, but this shows off the size and the mass really well.
July 21, 2013. Nikon D7100 (DX sensor), 70–300mm Nikon zoom lens at 70mm (35mm equivalent: 105mm), f/4.5, 1/8,000, ISO 1,100.
