A fixed arch bridge, that is one without hinges, exerts a bending moment at the abutments and stresses caused by change of temperature or shrinkage of concrete have to be taken up by the arch. A two-hinged arch has a hinge at the base of each arch (the springing point), while a three-hinged arch has a third hinge at the crown of the arch. [3]
The Causey Arch is a bridge near Stanley in County Durham, northern England. It is the oldest surviving single-arch railway bridge in the world, and a key element of the industrial heritage of England. It carried an early wagonway (horse-drawn carts on wooden rails) to transport coal. The line was later diverted, and no longer uses the bridge. [2]
The bridge is composed of five sequential wooden arch bridges on four stone piers as well as two wooden piers on the dry riverbed where the bridge begins and ends. Each of the three middle spans is 35.1 meters long, while the two end spans are 34.8 meters, for a total length of about 175 meters with a width of 5 meters. [1]

An arch bridge is a bridge with abutments at each end shaped as a curved arch.Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports.

A drawbridge or draw-bridge is a type of moveable bridge typically at the entrance to a castle or tower surrounded by a moat.In some forms of English, including American English, the word drawbridge commonly refers to all types of moveable bridges, such as bascule bridges, vertical-lift bridges and swing bridges, but this article concerns the ...
Built in 142 BC, the Pons Aemilius, later named Ponte Rotto (broken bridge), is the oldest Roman stone bridge in Rome, with only one surviving arch and pier. However, evidence suggests only the abutment is original to the 2nd century BC while the arch and pier perhaps date to a reconstruction during the reign of Augustus (27 BC – 14 AD). [ 39 ]
