The unusual bridges of Hillsdale County

Today it's called McCourtie Park, but back in the 1930s they called it Aiden Lair. And it sounds like it was a pretty sweet spot to stop and party if you happened to be a gangster traveling between Detroit and Chicago.

Cement tycoon W.H.L. McCourtie owned the property, a 42-acre chunk of land on US-12 in Hillsdale County. On the property was an unground bar - or rathskeller - that Dave probably would have like, except that McCourtie hosted famous Great Gatsby-esque bashes attended by the likes of Al Capone.

To decorate the landscape, McCourtie hired two Mexican artisans who specialized in sculpting concrete to look like wood - a skill called El Trabajo Rustico. Over a 10-year stretch they created 17 bridges that cross the creek on Aiden Lair, as well as other works that include two enormous tree trunks that served as chimneys for the underground bar's kitchen. The bridges are still there, and so are the tree trunks. The underground bar is left to your imagination.
