In 1893, the Wisconsin & Michigan began construction of a line from Peshtigo, Wisconsin to Faithorn, Michigan. This route went through some of the thickest forest that Northern Wisconsin had to offer.
It would cross the river at Koss on a large truss bridge.
In 1894, a number of branch lines would be constructed. This included a short lived one near Koss (abandoned 1895) and one from Constine, Wisconsin to Miscauno Island.
In 1895, the railroad would purchase a short narrow-guage line from Peshtigo to Peshtigo Harbor, Wisconsin. They converted this line to standard guage and used it as a port connection.
In 1903, the mainline would be extended north from Faithorn to Quinnesec, Michigan. The following year, a branch line would be extended from Miscauno Island to Everett, Michigan.
By 1908, the mainline would be completed to Iron Mountain where it would end.

The railroad was short lived, and the entire system was abandoned by 1938. However, much of the original railroad grade has been converted to highway use.
The bridges in the area at Koss and the three at Miscauno Island were all converted to vehicle use to help alleviate the lack of river crossings between Iron Mountain and Marinette.
Today, Miscauno Island remains an important reminder of the railroad history. The Four Seasons Resort has repaired and done upkeep to the three railroad bridges as reminders of history, while the Koss Bridge was demolished in 1991.


This bridge is one of three that cross over the Menominee River at Miscauno Island.

Miscauno Island is a very scenic and remote island located about 15 miles from Pembine, Wisconsin.
The other bridges, the West Bridge and the Middle Bridge are all very similar in design, and were built at the same time.

Fortunately, the Four Seasons Resort purchased the land in 1938 and converted the railroad bridges to serve cars.

In 2016, the bridge is in very good condition, however it does lie on private property. The photos above were acquired with permission.

The bridge is a 4 panel, riveted Warren Pony Truss. It sits on concrete substructures.

The bridge has been rated as regional significance by the author, due to the fact that it is one of only four surviving bridges from the Wisconsin & Michigan Railroad. The excellent preservation and unique structural details also contributed to this.

The photo above is an overview.

In addition to being related to the other two bridges on this island, the bridge also has another relative. A bridge in Peshtigo, Wisconsin has four spans with the exact same design as this structure.
