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 ...
In the 3rd century, segmental arch bridges, or flat arch bridges, emerged. One of the earliest examples of this type of bridge is the Limyra Bridge, [15] situated near Limyra in present-day Turkey. It is 360 meters in length and comprises 26 segmental arches and two semi-circular arches. [16]
An example is the Fremont Bridge in Portland, Oregon which is the second-longest tied-arch bridge in the world and also classifies as a through arch bridge. The Chaotianmen Bridge in Chongqing is a tied-arch, through arch and a truss arch bridge. Contrarily, the Hart Bridge uses a cantilevered trussed arch, it is self-anchored, but its arch is ...

Rossgraben bridge (Rüeggisberg) near Bern, Switzerland, showing the hinge at mid-span of this three-hinged arch. The practical arch bridges are built either as a fixed arch, a two-hinged arch, or a three-hinged arch. [103] The fixed arch is most often used in reinforced concrete bridges and tunnels, which have short spans.
The network arch type, with multiple crossings, i.e. overlap in the horizontal axis, was developed by Per Tveit to avoid this. [3] Lohse bridges have a tie conversely curved to the arch. The bridge deck is supported by a third structural element hanging underneath.
