"King bridge" is a term commonly used to refer to a type of truss bridge often seen in North America. This type of bridge was named after William King, a builder who popularized this design during the mid-1800s. While "king bridge" is the most common term used for this type of bridge, there are also a number of synonyms that can be used. These include "king post truss," "king post bridge," and "kingpost truss bridge." Each of these terms refers to the same type of bridge, with a central vertical post supporting the weight of the structure.
