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 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]
Pritchard died, aged 54, before the bridge was completed, but his design of The Iron Bridge led to the building of the first cast-iron arch bridge in the world.. He was buried in St Julian's, Shrewsbury, [1] where his monument also commemorates his wife, Elinor Russell, of Shrewsbury (married 1751, died 1768) and three children who died young.
The Chinese arch bridge reached its apogee in Fujian, where it was constructed with extremely thin arches. The Xiao Bridge, constructed in 1470, has a free height of 7.2 meters with an arch thickness of only 20 centimeters, which is half the thickness of a typical arch. [28] It remains in use today, supporting contemporary traffic.

Colorado Street Bridge, an example of a false skew arch. The strength of a regular arch (also known as a "square" or "right" arch) comes from the fact that the mass of the structure and its superincumbent load cause lines of force that are carried by the stones into the ground and the abutments without producing any tendency for the stones to slide with respect to one another.
