Abstract:Corrosion decay on structures has continued to be a challenge in the scientific
and engineering communities, where significant federal and state funds have
been spent towards replacement or rehabilitation of bridges that were damaged
by corrosion deterioration. In Maryland, a great portion of its yearly bridge
funding allocation is spent on performing repairs and rehabilitations on its aging
bridge inventory. In an effort to turn this trend around, the Maryland State
Highway Administration (SHA) has performed emergency span replacements
on two different bridges because the strands had deteriorated to such an extent
that serious safety concerns were exposed.
