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 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]
The first bridge, a wooden trestle, in 1864. The Erie Railroad Company built a wooden trestle bridge over the Genesee River just above the Upper Falls in the mid-1800s. Construction started on July 1, 1851, and the bridge opened on August 14, 1852. [2] At the time, it was the longest and tallest wooden bridge in the world. [3]
On April 6, 2001, the reconstructed wooden footbridge was opened, being the longest wooden bridge in Switzerland. The Kapellbrücke is a 204-metre-long (669 ft) bridge crossing the Reuss in the city of Lucerne in Switzerland. It is the oldest wooden covered bridge in Europe, and one of Switzerland's main tourist attractions. [citation needed]
The bridge opened for highway M-26 traffic in 1990, at which point the neighboring Lake Shore Drive Bridge was restricted to pedestrian use. [4] On August 26, 1992, the bridge was entered into the 1992 Timber Bridge Design and Construction Award Competition. [5] It was awarded first place in the "Long Span Vehicular Bridges" category. [6]
The design principle behind the Burr arch truss is that the arch should be capable of bearing the entire load on the bridge while the truss keeps the bridge rigid. Even though the kingpost truss alone is capable of bearing a load, this was done because it is impossible to evenly balance a dynamic load crossing the bridge between the two parts. [5]

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.
