By 1938, the D&IR merged with its partner, the Duluth Missabe & Northern Railroad to form Duluth, Missabe & Iron Range Railroad (DM&IR).
The DM&IR was a major iron/taconite hauler in the region, hauling the high grade Missabe Iron Ore to Lake Superior and to Pittsburgh.
United States Steel had control of the DM&IR until 1988, when they spun their railroad holdings off to Blackstone Group, who in turn sold them to Canadian National in 2003.
The DM&IR was a subsidiary of Canadian National until 2011, when it was fully purchased by Wisconsin Central, ending the long history of the railroad.
This line however was spun off to the Lake Superior Railroad Museum as a tourist/heritage railroad. The railroad currently operating the line is North Shore Scenic Railroad, which provides daily tourist railroads between Two Harbors and Duluth.
Today, the CN has trackage rights over this railroad, yet rarely uses them, unless a special case warrents it.
This high up little bridge is located next to 32nd Avenue in the upscale part of Duluth.
The bridge contains two deck girders that are each 30 Feet Long, put together in a continuous way on a steel tower. The approaches on either side are I-Beams, with one abutment being stone.
The bridge appears to be a local playground, with many nooks and crannies to explore. Including some that will break your leg if you aren't careful.
The reason this bridge was built is because of the stone bluffs underneath which made it necessary.
