Mega Underground Bike Park /
United States

The Mega Underground Bike Park has finally opened. This bike park is still in development but so far they have over 45 trails, jump lines, pump tracks, dual slalom, BMX, cross country and single track all packed into 320,000 square feet. Not only is this the only underground bike park but it is also the largest indoor bike park in the world!

“The quarry was mined for 42 years, on a 24-hour-a- day basis. It was the largest, most productive mine in all of Louisville from 1930 to 1972. Its location is dead center in the metropolitan area of Louisville. There are 223 limestone pillars that hold up the celling of the Mega Cavern. Each pillar is 26ft thick and composed of solid limestone...the hardest limestone in the U.S. You could stack every single building in Louisville on top of one another and the celling would not crack because it is rated for 60,000 psi! It’s as close to granite as you can get and is virtually impossible to break. For a real world comparison, the concrete that you drive across when you drive across a bridge is rated for 5,000psi.”

To learn more about the history of this cavern check out the visit we made there back in October just before they began building the bike park. (here) There are some other pretty cool things going on down there and it’s worth checking out.
