Beam Bridges are the simplest type of bridge today.
They are the direct descendent from the log bridge. It
is used often in pedestrian bridges and for
highway overpasses. Beam bridges are made of
one horizontal beam with two supports usually on
either end. Theses free standing bridges are usually
built as a walkway or even for decoration.
A cantilever bridge is a bridge built
using cantivelers, structures that project horizontally
into space, supported on only one end. For small
footbridges,the cantilevers may be simple beams; however,
large cantilever bridges designed to handle road or rail
traffic use trusses built from stuctual steel, or box girders
built from prestressed concrete.
An arch bridge is a bridge with abutments at each end
shaped as a curved arch. Arch bridges work by
transferring the weight of the bridge and its loads
partially into a horizontal thrust restrained by the
abutments at either side.
A suspension bridge is any type of bridge that makes
significant use of tension rather than or in addition to
compression. A suspension bridge usually has cables
(else ropes or chains), anchored at each end of the
bridge. Any load applied to the bridge is transformed
into a tension in these main cables
A truss bridge is a bridge composed of connected
elements (typically straight) which may be stressed
from tension, compression, or sometimes both in
response to dynamic loads. Truss bridges are one of
the oldest types of modern bridges. A truss bridge is
economical to construct owing to its efficient use of
The Verrazano-Narrows Bridge is a double-decked
suspension bridge that connects the boroughs of
Staten Island and Brooklyn on Long Island in New
York City. The bridge is named after an Italian explorer
named Giovanni de Verezzano, the first known European
navigator to enter New York and the Hudson River, while
crossing The narrows...
