ABSTRACT
The purpose of this thesis is to provide insight into how different geometric parameters such as tower

A study of 51 extradosed bridges shows the variability in proportions and use of extradosed bridges,
and compares their material quantities and structural characteristics to girder and cable-stayed bridges.

competitive designs.
