ABSTRACT
Currently, about 25% of highway bridges in the United States are considered either structurally deficient or functionally obsolete. Even though these deficient bridges are safe for the legal loads allowed on them, they are in need of corrective maintenance, repair, rehabilitation, or replacement to bring them to current standards with no load restrictions or inconvenience to the travelling public. This number is expected to increase due to limited capital funds available to reconstruct these aging bridges. In such a situation, an inspection program that can effectively address both safety and performance needs is required.
