In 1867, the Lake Superior and Mississippi Railroad (LS&M) began construction on a new railroad line, extending north from St. Paul, Minnesota to Duluth, Minnesota; a distance of 155 miles. The LS&M was sold to the St. Paul and Duluth Railroad (StP&D) in 1877. Known as the "Skally Line", the line became a principal connection between the Twin Ports of Duluth, Minnesota and Superior, Wisconsin. A major line change was completed in 1888, when the "Duluth Short Line" was constructed between Thomson and Duluth, and the original line reduced to a spur. The StP&D would be sold to the Northern Pacific Railway (NP) in 1900. NP operated this as their mainline between the Twin Cities and the Twin Ports. NP had a large network of railroad lines in Minnesota, and also had a network that extended to the Pacific Coast at Seattle.
In 1970, NP would merge with rival Great Northern Railway (GN) and the Chicago, Burlington & Quincy to form Burlington Northern Railroad (BN). The GN had a parallel route, and BN quickly began to favor that route. The first section abandoned was between Carlton and West Duluth in 1976. Further cuts came in 1977, when the segment between Hinckley and Moose Lake was abandoned. By 1980, the Moose Lake to Carlton segment would be abandoned. The segment between Hugo and Forest Lake would be abandoned 1987, and the segments from Forest Lake to North Branch and White Bear Lake to St. Paul abandoned in 1989. All of the abandoned segments would be acquired for recreational trail use. In 1996, BN merged with the Atchison, Topeka & Santa Fe Railway to form BNSF Railway. In 1997, BNSF would sell the Hinckley-North Branch segment to the St. Croix Valley Railroad (SCXY).
Today, the Minnesota Commercial operates a small segment from Hugo to I-694 and SCXY continues to operate the Hinckley-North branch segment. The Bruce Vento Trail utilizes the former railroad grade between St. Paul and I-694, while the Sunrise Prairie Trail utilizes the grade between Hugo and North Branch, and the Willard Munger State Trail utilizes the railroad between Hinckley and West Duluth. BNSF continues to operate small amounts of track in Duluth.
Located just east of County Road 61 in Pine City, this through plate girder bridge crosses the Snake River. Originally built in the 1880s as an iron truss, the truss bridge was replaced in 1906 by a 92-foot through plate girder span, set onto stone substructures. The bridge was also approached by wooden trestle on either end, and the girder featured a tapered edge, more typical of a Chicago & North Western Railway span. This design of bridge was commonly used by railroads throughout the United States, as it was durable and easy to construct. NP bridge records indicate that the north approach was rebuilt in 1955, and the south approach in 1958.
In 2009, shifting in the original sandstone piers, as well as a crack in the north pier, resulted in this bridge being closed from May to November of that year. The bridge was rebuilt in November 2009, with new concrete piers, and a new steel stringer span on the north end. The original trestle spans were also rehabilitated with new stringers. Overall, the bridge appears to be in good condition, with the repairs fixing much of the major deterioration on the bridge. The author has ranked this bridge as being locally significant, due to the common design.
