You enter the Atlantic Avenue Tunnel via a ladder through a manhole in the middle of Atlantic Avenue. Traffic is blocked off, but you should definitely wear comfortable shoes and those who are incapable of climbing up and down a 10 feet ladder should not plan on attending the event. We apologize for this, but there is absolutely no other way to enter or exit the tunnel. You must sign a liability waiver before entering the tunnel (forms will be available at the entrance). There are no chairs in the tunnel. We will put down tarps to sit on, and you are also welcome to bring small cushions (nothing too big, please). There are no bathrooms in the tunnel. You should use a restroom before you enter.
