content: Plate girders bridge are structural elements commonly used in bridge construction, industrial buildings, and other large structures. They consist of welded steel plates that form a deep, rectangular section capable of supporting heavy loads.

A tubular bridge is a bridge built as a rigid box girder section within which the traffic is carried.[1] Famous examples include the original Britannia Bridge over the Menai Strait, the Conwy railway bridge over the River Conwy, designed and tested by William Fairbairn and built by Robert Stephenson between 1846 and 1850, and the original Victoria Bridge in Montreal.
