FORM

Bridges are special among works of engineering in that their visual form is determined by a combination of technical and cultural considerations concerning both the relation of bridges to their environment and bridges as independent entities. A list of criteria which reflects this fundamental characteristic of bridges will be presented and illustrated by corresponding examples. For assessing aesthetic impact these criteria are very helpful, however, an improvement of the general standard of visual quality in bridges would necessitate reforms in education, design practice and administration of projects.
