While on top of the Mackinaw Bridge tollbooths I noticed one of the poles (east) is actually an antenna. I've seen the AM antenna towards the south end of the bridge and the repeater by the light pole by the Ignace exit but never noticed this.

How did you get up there? 
It might be one of those low power AM broadcasters with tourist information for the immediate area.

Control channel goes "brrrrr"
They also have a fairly active UHF Repeater for bridge management.
Bridge maintenance, sign control, receiver for WX sensors.

The low power AM stations are 530 on the Mackinaw City side and 1610 on the St. Ignace side.
Mackinaw Bridge Authority uses 453.95.
