This research addresses the feasibility of
constructing temporary, short-span (less than 100 feet) bridges on
existing piers and abutments expediently. There is an urgent need
to construct temporary bridges in natural disaster areas where main
bridges are damaged or destroyed. Erection of deployable and
reusable bridges on existing substructure is a cost-effective
alternative to retrofitting damaged bridges. When bridges are
damaged by floods and earthquakes, it can take months before the
transportation infrastructure is restored. To replace a damaged
bridge, a modular system that is easy to fabricate and build is
needed, i.e., a “bridge replacement kit,” with components ordered to
meet local specifications and installed in no time.
