[1] It is the oldest still-functioning bridge in Cambridge, built in 1639-40 by Thomas Grumbold (d.1659).

It is a three-span bridge in Early Renaissance style, built of Ketton stone ashlar.

The balustrade has carved relief panels on the pedestals and is surmounted by ball finials.

Many different tales are told to explain the missing section of the globe second from the left on the south side of the bridge.

The story most commonly cited by members of college is that the builder of the bridge was not paid the full amount for his work and so removed the segment to balance the shortfall in payment.
