The Milwaukee & Northern (M&N) reached Fort Howard, Wisconsin, in 1874.
In 1881, the M&N laid 24.4 miles of track from Fort Howard to a point 1 mile south of Stiles, Wisconsin.
The M&N constructed 15.1 miles of their main line from a point 1 mile south of Stiles to Coleman, Wisconsin, in 1882.
In 1883, the M&Nās main line was extended from Coleman to Wausaukee, Wisconsin, a distance of 22.2 miles.
In 1884, 9.8 miles of track were laid from Wausaukee to Station 3790 (later Pike, Wis., now Amberg, Wis.).
The line was extended 20.12 miles from Station 3790 (later Pike, Wis., now Amberg, Wis.) to Station 4852, on the Menominee River (the border of Wisconsin and Michigan), in 1886.
In 1892, the M&N constructed the Wausaukee Branch, running 17.7 miles northwestward from Wausaukee, Wis., to Girard Junction, Wis.
The M&N became the Superior Division of the Chicago, Milwaukee & St. Paul (CM&StP), or Milwaukee Road (MILW), on 1 July 1893. It reorganized as the Chicago, Milwaukee, St. Paul & Pacific (CMStP&P) in 1928.
Almost all of this portion of the former M&N main line is still active, operated by the Escanaba & Lake Superior (E&LS or ELS). The first three miles of this section, running from the Fox River to Bond St. in Fort Howard (now Green Bay), have been removed.
