A fog signal was erected here in 1890 to guide vessels through this narrow and dangerous strait. The increase in size and volume of vessel traffic almost immediately caused a need for a light on Mackinac Point. Located next to the Mackinac Bridge in Mackinaw City, Michigan, Old Mackinac Point Light, a brick two-story keeper’s dwelling with attached brick tower was completed in 1892. The tower is 6-feet in diameter and 40-feet tall.
