I played a recording of the Ann Arbor Children's House school kids and teachers signing the Mackinac Bridge Song (which was taught to all us kids back in the day)

The Mackinac Bridge Song

Chorus: Oh the Mackinac Bridge (oh the Mackinac Bridge) She’s a mighty fine bridge ( she’s a mighty fine bridge) Five hundred feet high (five hundred feet high) and five miles long (and five miles long)

Verse 1- In the straits of Mackinac there’s about as much water as you ever saw and the folks who lived there tried and tried but the couldn’t get across to the other side, couldn’t get across without a boat or a plane couldn’t get across without out a trolley or a train couldn’t swim across it was as cold as a fridge! So they thought they better build themselves a bridge.

Verse 2- So in nineteen hundred fifty-four they started linking shore to shore from Mackinaw city to St. Ignace town, and the men on the top didn’t dare look down! In fifty-seven the work was through, and there she was all shiny and new so they had a big party and they called out loud

“She’s the Mackinac Bridge and we are proud!”

Chorus
