Ultimate Guide to The Mathematical Bridge

It was originally designed in 1748 by William Etheridge, and built in 1749 by James Essex the Younger. Initially the bridge stood on the site where Garret Hostel Bridge, but it now connects the old Tudor part of the college to the new Erasmus buildings on the opposite side of the Cam. The bridge has actually been rebuilt twice (in 1866 and 1905) due to the aging of the timber, but its design remained unchanged.

The Mathematical Bridge is surrounded by a surprising number of myths and falsehoods, which is rather surprising considering how well-documented its history is. Contrary to popular legend, the bridge WAS NOT:

• designed or built by Sir Isaac Newton (he died in 1727)
• constructed without the need for nuts and bolts (a structure of this shape and this size would not be possible without iron bolts or fastenings)
• originally named ‘Mathematical Bridge’ (College documents refer to it as either the ‘Essex bridge’ or the ‘wooden bridge’)

The bridge can be accessed from the porter’s lodge on Silver Street, for £3.50. You can find out more about the Mathematical Bridge and other amazing sights in Cambridge by checking out our amazing University & City Tour!
