The strength and growth of the nation's economy are intimately
linked to the strength of our highways and bridges. Among
industrialized nations, the U.S. has the largest number of
bridges, 590,040, according to "Better Roads" (November
1997). Of these, 179,455 (30.45%) are structurally or functionally
deficient. In 1992, the cost of replacing deficient bridges
was estimated at $78 billion, while bridge expenditures for
the same period, excluding new construction, were approximately
$5 billion from all sources; federal, state and local.
The replacement, retrofit and maintenance of deficient bridges
provides a challenge to state, federal, and local agencies
as well as to industry and academia. To resolve these challenges
it is prudent to assemble a multidisciplinary group with members
having various expertise covering both engineering and social
science fields. A model in which the cooperation of all interested
groups is ensured from the onset would be ideal. The establishment
of the National Bridge Research Organization (NaBRO) at the
University of Nebraska-Lincoln is an attempt to provide such
a platform. In fostering cooperation between academia, industry
and government agencies NaBRO will be a liaison in developing
and implementing new technologies related to bridge design
and construction. Through recent years the State of Nebraska,
together with the neighboring States of Kansas, Iowa and Missouri,
has taken the lead in developing and implementing many new
ideas in the field of bridge engineering. The first High Performance
Steel Bridge constructed in the U.S. and opened to traffic
is located in Nebraska. The first High Performance Concrete
Bridge to open to traffic is also located in Nebraska.
The researchers at NaBRO are in the forefront of resolving
design issues that will facilitate the use of high performance
steel in bridge construction. These and other research accomplishments
of the affiliated researchers are the reasons for great optimism
for the future of NaBRO. At NaBRO we are excited to have the
opportunity to work towards developing new knowledge and resolving
issues related to bridge engineering. We also hope that the
bridge industry will consider NaBRO a source through which
they can find solutions to complex and challenging bridge
engineering problems and provide us with feedback so that
we may enhance our productivity.
