Approximately 500 feet from the west edge of the Milford Mine Historic District, a 700-foot-long trestle carried the rail line over an inlet of Island Lake. Although the trestle no longer exists, footings from some of its bents are still visible. East of the trestle, 2,000 feet of rail grade was built up with fill as the line crossed the wetlands that now form the north shore of Milford Lake. To the west, a 700-foot-long trestle carried the Soo Line track over an inlet of Island Lake, and footings from some of its bents remain visible just above the water's surface.
