The Mathematical Bridge, officially known as the Wooden Bridge, is one of Cambridge’s most recognisable landmarks, spanning the River Cam at Queens’ College. First built in 1749 to a design by William Etheridge and constructed by James Essex, it has been rebuilt twice, in 1866 and 1905, following the original plans. Ingeniously engineered, the bridge appears to form a graceful arch, yet is made entirely of straight timbers arranged using precise geometric principles, creating both strength and elegance. Its name reflects the mathematical skill behind its tangent and radial truss design, which minimises bending forces and maximises stability. A popular myth claims it was built by Sir Isaac Newton without bolts or nails, but in reality it has always been fastened with metal fixings—Newton had died decades before its construction. Offering picturesque views of the river and surrounding college buildings, the Mathematical Bridge remains a symbol of Cambridge’s blend of scientific ingenuity, architectural beauty, and enduring tradition.
Cambridge United KingdomThe Mathematical Bridge is a distinctive wooden footbridge located in the southwest of central Cambridge, spanning the River Cam to connect two parts of Queens' College. It stands about 100 feet northwest of Silver Street Bridge and links the older Tudor section of the college with the newer Erasmus Building. The bridge was designed by William Etheridge and built in 1749 by James Essex, and despite its arch-like appearance, it is composed entirely of straight timber beams arranged in a sophisticated tangent and radial trussing system for structural integrity. Nearby on one side is the 15th-century President’s Lodge, part of Queens' College, and the bridge can be viewed from Silver Street, a prominent riverside street in Cambridge. For visitors, the nearest transport hub is Drummer Street bus station in the city centre, and limited parking is available near Queens’ College. The Mathematical Bridge is a Grade II listed building and a celebrated example of 18th-century engineering surrounded by the historic ambiance of Cambridge University’s riverside.
