This wooden bridge connects the two parts of Queens' college in Cambridge. This bridge was built in 1906, replacing an earlier bridge from 1749 (which had seen repairs in 1866). But the later version kept the original design (designed by William Etheridge and built by James Essex the Younger), using straight timber but at the same time creating the allusion of an arch.
The rather unusual design of the bridge has given it its current popular name of the Mathematical Bridge - but as Queens' college themselves point out on their website: "There is no such thing as an “official name” for the bridge. It has never been named." In the 18th century it was known as “Essex’s Bridge”, it was later also known as “Newton’s Bridge” because it was erroneously believed he had designed the it. The bridge was sometimes called the Mathematical Bridge from 1803 onwards - but there was also another Cambridge bridge known by that name. But the bridge is also known as the "Queens' bridge" - the above mentioned website calls it both the Mathematical and Queens' bridge.
If you are really in to bridges I must recommend the college web-page on the subject, it is extensive and very informative.

The Penrose Paving is constructed from just two different diamond-shaped granite tiles, each adorned identically with stainless steel circular arcs. There are various ways of covering the infinite plane with them, matching the arcs. But every such pattern is non-repetitive and contains infinitely many exact copies of what you see before you.

The Mathematical Bridge, also known as Newton's bridge, Queen's College Cambridge UK. It looks like an arch but is made of straight timbers.
Thank You Deep Dream Generator. Yes I was a math nerd back in the days. I hope I don't bore you with this series.

The bridge was designed by William Etheridge, and built by James Essex in 1749. It has been rebuilt on two occasions, in 1866 and in 1905, but has kept the same overall design. Although it appears to be an arch, it is composed entirely of straight timbers[4] built to an unusually sophisticated engineering design, hence the name.
A sunny day in late September and people enjoying punting on the River Cam in Cambridge. The wooden bridge spans over a hundred feet linking two parts of Queens' College. It is a Grade II listed building built in 1749 by James Essex. It has been rebuilt on two occasions in 1866 and 1905 but kept the same design. It is built of straight timbers to a particular engineering design hence its name.
The Mathematical Bridge is the popular name of a wooden footbridge in the southwest of central Cambridge. It bridges the River Cam and joins two parts of Queens' College.

I have always granted myself the freedom to exercise artistic license and pursue whatever brings me joy. Currently, shots from my cellphone and digital AI artwork fulfill that purpose, at least for the time being.
If in doubt which is my work and which is Generative AI, just look for the watermark on my photography.

The Mathematical Bridge is the popular name of a wooden bridge across the River Cam, between two parts of Queens' College, Cambridge. Its official name is simply the Wooden Bridge.
The bridge was designed by William Etheridge, and built by James Essex in 1749. It has been rebuilt on two occasions, in 1866 and in 1905, but has kept the same overall design.
The original "mathematical bridge" was another bridge of the same design, also designed by James Essex, crossing the Cam between Trinity and Trinity Hall, where Garret Hostel bridge now stands.
A oft shot image of the Mathematical Bridge in Cambridge. Nothing original here, but why not, like thousands of other photographers!
X I am no mathematician or builder all I can say is this bridge looks wonderful. I have enclosed some information on the design that I do not fully understand myself but some of you will no doubt
The Mathematical Bridge is the popular name of a wooden footbridge in the southwest of central Cambridge, United Kingdom. It bridges the River Cam about one hundred feet northwest of Silver Street Bridge and connects two parts of Queens' College. Its official name is simply the Wooden Bridge. It is a Grade II listed building.
The bridge was designed by William Etheridge, and built by James Essex in 1749. It has been rebuilt on two occasions, in 1866 and in 1905, but has kept the same overall design. Although it appears to be an arch, it is composed entirely of straight timbers built to an unusually sophisticated engineering design, hence the name.
The arrangement of timbers is a series of tangents that describe the arc of the bridge, with radial members to tie the tangents together and triangulate the structure, making it rigid and self-supporting. This type of structure, technically tangent and radial trussing, is an efficient structural use of timber, and was also used for the timber supporting arches (centring) used for building stone bridges. Analysis of the design shows that the tangent members are almost entirely under compression, while the radial timbers are almost entirely subject to tension with very little bending stress, or to put it another way, the tangent and radial elements elegantly express the forces involved in arched construction.
THANKS FOR YOUR VISIT AND FOR TAKING THE TIME TO WRITE A COMMENT IT’S MUCH APPRECIATED.

The bridge was designed in 1748 by William Etheridge (1709–76), and was built in 1749 by James Essex the Younger (1722–84). It has subsequently been repaired in 1866 and rebuilt to the same design in 1905.
The myth that the bridge was originally built without fastenings at the joints, but could not be rebuilt successfully without introducing fastenings at the joints, might owe its origin to a change in the nature of the fastenings during the 1905 rebuilding.
Although it appears to be an arch, it is composed entirely of straight timbers built to an unusually sophisticated engineering design, hence the name. A replica of the bridge was built in 1923 near the Iffley Lock in Oxford.
Sited next to Queens College, this wooden bridge over the River Cam was originally built in 1749, and was rebuilt in 1905 to the same design. It is an example of a voussoir arch bridge.

According to Wikipedia:
"Popular fable is that the bridge was designed and built by Sir Isaac Newton without the use of nuts or bolts, and at some point in the past students or fellows attempted to take the bridge apart and put it back together" (and had to use bolts).
However, "this story is false: the bridge was built of oak in 1749 by James Essex the Younger (1722–1784) to the design of the master carpenter William Etheridge (1709–1776), 22 years after Newton died."
The riverside building to the right dates to around 1460.

The riverside building on the right centre dates to around 1460, and is the oldest building in Cambridge by the River Cam.
Inside the Mathematics Institute at Oxford. We were privileged to be given a tour of this extraordinary building. Very Escher like in it's communications corridors - except they all go somewhere! Full of light which is channelled to the different floors via glass crystal shaped structures which give fabulous reflections. It is an amazing structure. What a place for some of the best brains to flourish!!!
