More of the mechanics of the Mystic River drawbridge. There’s a large “Bull wheel” and spur gear that makes the bridge pivot on some very large pillow block bearing. Two counterweights weighing 1,140,000 pounds attached to the top of the bridge help to counterbalance the bridge as it’s being raised and lowered. It’s an amazing piece of American engineering and bridge history and even more fun to watch it in action! #abom79 #mysticdrawbridge #drawbridge #bridge #engineering #mystic #mysticconnect
