Bridges are spaces. Bridges are places, where people meet other people, enjoy their surroundings, and experience being part of a community. Though a mode of transit, bridges can be magnets for public activity and fun. Bridges not only connect land to land, but also have an impact on adjacent parks, industries and residential communities, and interact with the city’s transportation infrastructure. Andrea Palladio, the great 16th century Italian architect and engineer, hit on the essence of bridge building when he said “…bridges should befit the spirit of the community by exhibiting commodiousness, firmness, and delight.”
Bridge: n. a structure carrying a road, path or railway across a river, road, etc.
Origin: OE Brycg, of Gmc origin.
National Bridge Inspection Standard (NBIS) defines a bridge as a structure of length 20 feet or greater
Bridges have played an important role in the history of human settlement. The first bridges were natural, such as the huge rock arch that spans the Ardèche in France, or Natural Bridge in Virginia (USA). The first man-made bridges were tree trunks laid across streams in girder fashion, flat stones, such as the clapper bridges of Dartmoor in Devon (UK), or festoons of vegetation, twisted or braided and hung in suspension found in India, Africa and South America. As the time passed, horses became plentiful; wagons and carriages were available; roads were built. Then it was that the rivers became barriers to transportation. Ferries were established and did very well for a while, but eventually it became evident that bridges must be built.
While artists and engineers, cities and countries compete to build technological masterpieces spanning across rivers, oceans or connecting cities and countries; people come up with innovative ways of using them. Though designed and built by the Department of Transportation, bridges are a peoples’ domain.
