The bridge itself is a 109.9 feet (33.5 m) long and 22.75 feet (6.93 m) wide, supported by abutments on either side of concrete on the upper level and stone laid in a random ashlar pattern below. Its main components are the two top and two bottom chords. [2] View of bridge from side

  4. Inverted arch - Wikipedia

    en.wikipedia.org/wiki/Inverted_arch

    The conventional arch supports a vertical load downwards on the centre of the arch and translates this into forces both downwards and outwards at the base of the arch. In most cases, this sideways force is a nuisance and must be resisted by either strong foundations or a further 'bowstring' girder, in the form of a tied-arch bridge .

  5. Pier (bridge structure) - Wikipedia

    en.wikipedia.org/wiki/Pier_(bridge_structure)

    Most of the piers of modern bridges are made of reinforced concrete or prestressed concrete for larger structures. Two types of forms are mainly encountered: columns or walls. Each support can be composed of one or more walls or columns. The standard-shaped walls that can be found on most highways are represented in the illustration opposite.

    en.wikipedia.org/wiki/Rigid-frame_bridge

    Prestressed concrete is a major advance in concrete engineering and has effectively been used in rigid frame bridge construction. [10] This is notable because it was already challenging to place standard reinforcing in a concrete rigid frame bridge. Prestressing the rebars is more difficult but was proven to still be feasible. [10]

  9. Skew arch - Wikipedia

    en.wikipedia.org/wiki/Skew_arch

    Colorado Street Bridge, an example of a false skew arch. The strength of a regular arch (also known as a "square" or "right" arch) comes from the fact that the mass of the structure and its superincumbent load cause lines of force that are carried by the stones into the ground and the abutments without producing any tendency for the stones to slide with respect to one another.
