Girder bridges have existed for millennia in a variety of forms depending on resources available. The oldest types of bridges are the beam , arch and swing bridges, and they are still built today. These types of bridges have been built by human beings since ancient times, with the initial design being much simpler than what we utilize today.
Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site.

Drawing of the bridge showing span and transporter car. The two towers were 180 feet (55 m) high and the distance between them spanned by a truss was 1,000 feet (300 m). The weight of the cables suspending the girder was 250 tons. The underside of the girder was 82 feet (25 m) above the high water level.
The bridge was officially dedicated as the Pearl Harbor Memorial Bridge in 1995 to commemorate the attack on Pearl Harbor. [2] The old Pearl Harbor Memorial Bridge was replaced by a $554 million 10-lane extradosed bridge; the northbound span of which opened to traffic on June 22, 2012. Southbound traffic was shifted onto the new bridge, sharing ...
The (non-modular) box girder bridge was a popular choice during the roadbuilding expansion of the 1960s, especially in the West, and many new bridge projects were in progress simultaneously. A serious blow to this use was a sequence of three serious disasters, when new bridges collapsed in 1970 ( West Gate Bridge and Cleddau Bridge ) and 1971 ...

A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel, a Belgian engineer who proposed this new bridge girder-type without diagonals in 1896. [ 1 ] Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints .
