-== '''Bridges''' ==
-'''Introduction'''
-A bridge is a means by which a road, railway or other
-service is carried over an obstacle such as a river, valley,
-other road or railway line, either with no intermediate
-support or with only a limited number of supports at
-convenient locations.
-Bridges range in size from very modest short spans
-over, say, a small river to the extreme examples of
-suspension bridges crossing wide estuaries.
-Appearance is naturally less crucial for the smaller
-bridges, but in all cases the designer will consider the
-appearance of the basic elements which make up his
-bridge, the superstructure and the substructure, and
-choose proportions which are appropriate to the
-particular circumstances considered. The use of steel
-often helps the designer to select proportions that are
-aesthetically pleasing.
