I have been opening drawbridges for a living for 18 ½ years. I’ve operated 9 different bridges in three states. I’ve operated bascule bridges, lift bridges, and swing bridges. I’m pretty proud of those statistics. I can only think of one bridgetender in this country who can (by just one bridge) beat that, and he’s now retired.
But here’s something I’ve never done until recently: I’ve never been down below, deep in the mechanical inner workings of a drawbridge, while a bridge opening was in progress. I knew what happened down there, because I have to help maintain the equipment, and I know what each moving part does. But I’ve never actually gotten to witness it in all these years, because it was always me operating the bridge during the opening. You can’t be two places at once.
Well, finally, a few weeks ago, I got to be down below while someone else was doing the driving. I was so excited! And of course I wanted to take videos to share with all of you.
My first concern had to be for my safety. There is about a million pounds of moving concrete and steel down there. Stand in the wrong place, and you can be partially or entirely crushed. That’s why we are always extremely cautious when there are workmen on the bridge, and will not do an opening unless we are assured that each one is in the clear.
So, after assuring my coworker that I was in a safe place, he commenced with the opening. I chose to be standing on a portion of the catwalk that is suspended above the pit where the counterweight sinks into the ground when the bridge goes up. This catwalk does not move, but the entire room basically spins around it.
Wow, what a rush. To see a drawbridge doing its well-choreographed dance everywhere you look is like nothing else on earth. I was suddenly proud that I’ve been part of this dance for all these years. It’s beautiful. I actually got tears in my eyes. Sniffle.
Anyway, I did manage to take these videos for your viewing pleasure. I wish I could adequately explain what’s going on. I know the lighting is poor, and I couldn’t get a good angle that would give you a better sense of where I was and what exactly is going on. I did the best that I could.
In the first one, you see the pinion (a large gear), rolling down the rack during the bridge closure. This is what allows the bridge to move. There’s another behind me, and a set on the north side of the bridge that is doing the same thing to operate the other bridge leaf. The counterweight (to the right) is lifting up, and the bridge leaf (out of sight to the left) is lowering down.
In the other video, I’m standing in basically the same place, but I’ve turned to look out towards the water. This one was taken as the bridge was opening for a boat. You’ll see the bridge leaf lift up, and a sailboat go through. You can also see the other leaf, on the other side of the water, lifting as well. In this one, the counterweight is dropping down behind me, and the pinions are also out of sight, but are rolling to the left and right of me. That’s when I started getting all sentimental. I just love my bridge.
I hope this makes at least a little sense, and that you enjoy seeing a drawbridge from a whole new point of view!
