The single arch of the bridge has a span of 31.4 meters and a rise of 11.42 meters, which was unusually flat for the time. The structure features two different masonry techniques: the lower part is made of gneiss blocks, dry-laid, while the upper part is a superposition of layers made of gneiss flakes and lime, interspersed with bands of stone.

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.
The through arch bridge usually consists of two ribs, [5] although there are examples like the Hulme Arch Bridge of through arches with a single rib. When the two arches are built in parallel planes, the structure is a parallel rib arch bridge. When the two arch ribs lean together and shorten the distance between the arches near the top, the ...
This diagram was created with Inkscape. This SVG diagram shows a very simple image. Drawing uncomplicated graphics with a text editor seems more adequate than using a vector graphics program, and will often result in a dramatic reduction of file size.
If horizontal thrust is generated but the apex of the arch is a pin joint, this is termed as a three-hinged arch. If no hinge exists at the apex, it will normally be a two-hinged arch . In The Iron Bridge shown below, the structure of each frame emulates the kind of structure that previously had been made of wood .
A tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch(es) are borne as tension by a chord tying the arch ends rather than by the ground or the bridge foundations. This strengthened chord may be the deck structure itself or consist of separate, independent tie-rods.
A hinged arch bridge is one with hinges incorporated into its structure to allow movement. In structural engineering, a hinge is essentially a "cut in the structure" that can withstand compressive forces. In a steel arch the hinge allows free rotation, [2] somewhat resembling a common hinge. The most common hinged arch bridge varieties are the ...
