This crossing did not exist long because the CS was purchased by Vanderbilt interests and truncated just east of the crossing. But the location survived in a different way as north and south wye tracks were connected to the Michigan Central main line.
When the Detroit & Toledo Shore Line (GTW/Nickle Plate) built their own line parallel east of the NYC/MC line, the former CS wye tracks crossed the D&TSL and two interlocking towers were built. These were eventually reduced to one tower on the north leg which was used to shuttle MC trains off Grosse Isle to Detroit until the international tunnel was built in Detroit about 1907.
