Roll Up Bridge
By Mark Flippo
Every Friday at midday, the Rolling Bridge in London furls to allow a boat to pass in or out of its moorage. The bridge consists of eight triangular sections hinged at the walkway level and connected above by two-part links that can be collapsed towards the deck by hydraulic cylinders, which are concealed in vertical posts in the bridge parapets. When extended, it resembles a conventional steel and timber footbridge, and is 12 metres (39.37 feet)long. To allow the passage of boats, the hydraulic pistons are activated and the bridge curls up until its two ends join, to form an octagonal shape measuring one half of the waterway's width at that point.
I can remember my folks talk about a small town after dark. "They roll up the sidewalks"! I could never get any sidewalk to roll up when I was seven. Now I understand what they meant. What a genius idea! Could you ever imagine this? What will God permit us to do? I am excited, are you?
