A51 Update: Lower Main Street is Open for Business

By Travis Poulin


A51 has gone big with the expansion of Lower Main Street. Cruising down Maine Street is no Sunday drive though as the features are huge! If you have what it takes, go check out the return of the A51 basketball hoop bonk, a large pole jam with plenty of potential for air, or a sweet up-box that will send you flying. Lower Main Street also features a C-rail, a gap to flat-down tube, an up-flat-down rail, and a pill on a hip where you can get creative!


The 18 foot quarter pipe is also open and ready for you to go as big as you want!


Don’t forget, you don’t have to hit these giant features; you have plenty of options from tiny boxes to medium sized rails, and jumps of all sizes. So whether you’re a little ripper or a park pro get on out to A51 and enjoy because this incredible park has something for everyone.


Stay tuned with the A51 Facebook page for updates of new features, park news and events.
