Underground bicycle park being built in old Kentucky mine

It's the perfect setting: millions of tons of dirt, plenty of space and an atmosphere that stays at a constant 58 degrees.

A new underground bicycle park with miles of dirt trails, jumps and stunt courses is being built inside an abandoned limestone mine in Louisville that has been recycled into a popular tourist attraction. The owners of the 320,000-square foot park say it will be the largest indoor course in the nation.

"We have a very large area to work with," said Tom Tyler, who co-owns the former mine, now called the Mega Cavern. "You can't duplicate it. Somebody would have to go out and dig rock for 40 years before they have what we've got here."

The Mega Cavern is also used for salt storage by KYTC.

And as a zip line. It's an amazing place.

Maybe that's what they should do with Seattle's Alaska Way Tunnel.
