We stand at the base of the South side tower facing east, and the sun is dipping in the sky behind us. Ornate stonework and leaded windows loom above. On the left are the undersides of the road and upper foot bridges with the metal bracing visible on the right. Tower Bridge is a marvel to behold in action. The lower bridge opening to allow tall river traffic through. I took some video of the bastules in action on the day the reference image was taken, as I was lucky enough to see it in action. It’s amazingly fast, even for modern day engineering, and especially considering much of the action is over 100 years old and still going strong.
