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.
Patent image for Marsh's Reinforced Arch Bridge Brush Creek Bridge. James Barney Marsh (April 12, 1856 – June 26, 1936) was an American engineer and bridge designer. He patented a new design for arch bridges. Marsh gave Archie Alexander, the first African-American to graduate as an engineer from Iowa State University, his first job.
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]
The actual resolution of forces will depend upon the bridge' design. [1] If no horizontal thrusting forces are generated, this becomes an arch-shaped truss which is essentially a bent beam – see moon bridge for an example. If horizontal thrust is generated but the apex of the arch is a pin joint, this is termed as a three-hinged arch.
The Godavari Arch Bridge is a bowstring-girder bridge that spans the Godavari River in Rajahmundry, India. It is the latest of the three bridges that span the Godavari river at Rajahmundry. The Havelock Bridge being the earliest, was built in 1897, and having served its full utility, was decommissioned in 1997.
The arch itself is 244.1 metres (801 ft) long and was the longest arch in Europe at the time of construction. [ 1 ] Unlike many other bridges from the same period and with the same construction, like the IJsselbrug near Zwolle , the Graafsebrug and the John Frost Bridge at Arnhem , the Waalbrug is an arch bridge in the literal sense: all forces ...

The 1923 report "Construction of a Concrete Railway Viaduct in Ceylon", published by the Engineering Association of Ceylon, has details of all the records including the plans and drawings. [7] Folklore generally attributed the construction of the bridge to a local Ceylonese builder, P. K. Appuhami, in consultation with British engineers.
