Town licensed his design at one dollar per foot - - or two dollars per foot for those found not under license. Additional related info is found on the other the four main factors are used in describing a bridge. This theme section seeks to bridge the gap between geospatial science and marine conservation by discussing the use of innovative approaches to support effective marine conservation planning strategies for pelagic ecosystems.

Geospatial technologies are critical for the successful design of pelagic conservation areas, because they provide information on the spatially and temporally dynamic oceanographic features responsible for driving species distribution and abundance in the open ocean, the movements of protected species, and the spatial patterns of distribution of potential threats. The is a very common type, but has many variations. The placement of the deck in relation to the superstructure provides the descriptive terms used in all bridges deck, pony, and through.

By combining these terms one may give a general description of most bridge types. Once constructed of wooden timbers, and later including iron tension members, most truss bridges are built of metal. Pratt and warren bracing are among the most commonly used truss types. Army topographical engineers sent to explore and map the united states as it expanded westward.

The whipple truss was most commonly used in the trapezoidal form -- straight top and bottom chords -- although bowstring whipple trusses were also built. Types of truss bridges are also identified by the terms which describe the placement of the travel surface in relation to the superstructure (see drawings above).

The basic identifying features are the diagonal web members which form a v-shape. A through arch is shown, but this applies to all type of arch bridges. Many later covered bridge truss types used an added arch based on the success of the burr truss. .

    Though pittsburgh has been a pioneer in bridge design and fabrication, it has had few suspension bridges.
