In 1884, the Wisconsin Central Railway built a route heading east of St. Paul towards Wisconsin.
An additional route was built in 1888 by the Wisconsin Central, connecting to the junction of the Minneapolis, St. Paul & Sault Ste. Marie Railway in Minneapolis.
A spur to the St. Paul Union Depot from Little Canada was constructed in 1906. The Wisconsin Central remained independent until 1961, when it formally merged with the MStP&StM to form the Soo Line.

In 1982, the Soo Line abandoned a portion between St. Paul and Oakdale. This segment has largely become the Gateway State Trail.
In 1985, the Soo Line was purchased by Canadian Pacific. The Minneapolis-Stillwater portion was sold to Wisconsin Central Ltd, and became Canadian National in 2001.

This beautiful truss bridge once carried Soo Line passengers to and from Wisconsin into the St. Paul terminal.
Presently, it only serves a spur with little to no traffic. It formerly crossed a Northern Pacific mainline, now BNSF.
The bridge itself is a heavily skewed, 6 panel, pin connected Warren Through Truss. The truss contains a combination of rivet plates and pin connections. It sits on concrete substructures.
Overall, the bridge appears to be in fair to good condition, with minor deterioration noted. Should this bridge become disused, it could become part of a recreational trail.
It is a very concealed structure, sitting in an industrial area. It can be seen from the Jackson Street Bridge, or by permission from property owners.

The author has ranked this bridge as being moderately significant, due to the truss design.
