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 two span concrete arch carries the Gateway Trail over the Keller Lake outlet along Frost Avenue.
Built in 1906 across a channel flowing out of Lake Phalen, the bridge features a pair of concrete arch spans. These spans rest on concrete substructures.
This bridge features a common design. Overall, it appears to be in poor condition. Major cracks have developed in the superstructure.
The author has ranked this bridge as being locally significant, due to the common design.
