Interlocking: Detroit, MI - Milwaukee Junction Tower

Milwaukee Junction Tower Milwaukee Jct Tower

Milwaukee Jct Tower Detroit Milwaukee Jct Tower DetroitNorthbound View of Milwaukee Junction Milwaukee Junction tower controlled the crossing of Grand Trunk ( Detroit to Grand Haven cross-state line) and  the crossing of the GTW wyes where they crossed the Michigan Central Bay City branch. This was a MC tower. The tower was one of the last closed in the Detroit area, finally eliminated in the early 2000's. As you can see by the interlocker model board, the GTW Mt. Clemens sub (West Detroit to Port Huron) was not controlled except for the wye switches.
