Architecture
A queen-post bridge has two uprights placed about one-third of the way from each bank. They are connected across the top by a beam and use a diagonal brace between the outer edge. The central square between the two verticals was either unbraced on shorter spans, or had diagonal braces from the bottom of each queen post to the center of the upper cord. The deck is supported by a king post, which is held up by a triangular truss.
An alternative truss construction used a pair of cross beams between the queen posts, forming an "X". This is then considered a Warren truss.

Famous quotes containing the word architecture:
“I don’t think of form as a kind of architecture. The architecture is the result of the forming. It is the kinesthetic and visual sense of position and wholeness that puts the thing into the realm of art.”
—Roy Lichtenstein (b. 1923)
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
“The two elements the traveler first captures in the big city are extrahuman architecture and furious rhythm. Geometry and anguish. At first glance, the rhythm may be confused with gaiety, but when you look more closely at the mechanism of social life and the painful slavery of both men and machines, you see that it is nothing but a kind of typical, empty anguish that makes even crime and gangs forgivable means of escape.”
—Federico García Lorca (1898–1936)
