The mathematical bridge is an 18th century wooden footbridge that connects Queens’ College across the Cam river. Although it seems to be an arch, it is composed entirely of straight timbers built to a sophisticated engineering design, hence the name. Can you see that the arch is made up of only straight timbers?
Local myths talk about how the original bridge had no nuts of bolts, and how no one could put it back together once it was taken apart. However, these stories are almost totally untrue. The beauty of the design of this bridge lies in how the arch has been created to create the effect of a standard bridge.
