The 216-foot draw-span section has been inoperable since Feb. 28, 1961, because other low bridges on the river prevented navigation by taller ships.
I am disappointed that the drawbridge doesn't function anymore. When the very old bridge had its final operation in the 1960's, this drawbridge will no longer open. But the drawbridge didn't had a traffic light or gates. I hope this bridge gets rebuilt as a replacement drawbridge.
Found this blog post with a photo of this bridge being built - just the formwork was up.
