Five construction workers died during the construction of the Mackinac Bridge. Two fell approximately 550 feet from a
temporary catwalk near the top of north tower, one died in a diving accident, one fell in a caisson while welding and
one drowned after a short fall into the water. One body was not found after the two workers fell from the temporary
catwalk. Despite the popular myth, there are no bodies buried in the concrete piers of the Mackinac Bridge.

Mackinac Bridge from the air

The lighthouse was decommissioned in 1957 when the lights on the Mackinac Bridge made it no longer necessary. It is a museum today.

Mackinac Bridge construction in winter
As the work is suspended for the winter of 1956-57, the bridge roadway is nearly completed up to the two anchorages.

Mackinac Bridge catwalk and cable
The finished Mackinac Bridge cables are 24.5 inches thick, too heavy to be floated into place, so they were constructed in place
