The Northern Avenue bridge was illuminaled in orange and blue but I didn’t get even halfway across when a security guy called out that we had to clear the bridge because it was going to open. Open? I had no idea it could. Turns out it’s the spinny kind of drawbridge. Here are some shots from the adjacent Moakley bridge as the Northern ave slowly turned to admit an invisible ship.
Update: check out Lance’s different perspective on the same bridge swing.
