This small stone arch bridge was built in approximately 1890, as a joint venture between a number of railroads.
The stone arch is a common design, with a concrete liner. One unique feature is the large stone wall on the west side.
This is due to another track formerly curving off. This arch forms part of the south abutments of the 4th Street Bridges.
The bridge appears to retain excellent historic integrity. Trout Brook is covered for much of its length through the railroad area of St. Paul.
The photo above is an overview of the west end.
The author has ranked this structure as locally significance because of its small size, and later example of a Stone Arch.
