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, also known as the Natchez Trace Parkway Arches, is the first segmentally constructed concrete arch bridge in the United States. [2] The arches comprise 122 hollow box segments precast in nearby Franklin, each of which was about 9.8 ft (3.0 m) long and weighed between 29 and 45 short tons. [2]

The bridge has a main span of 37 metres, and a total length of 55.6m. [2] The arch is polygonal rather than curved, and is only 200 mm thick. [3] It supports the bridge deck via 160 mm thick reinforced concrete cross walls. The deck is thicker than the arch, and is stiff enough to prevent the slender arch from buckling. The highway deck is ...
For example, his Crestawald Bridge (1959) was a reinforced concrete bridge with a two-hinged arch. [4] But with the revolutionary new material — prestressed concrete — Menn saw that prestressing could actually replace the arch itself. The prestressed deck of his arch bridge could become the main supporting member without the arch.
