The laboratory is used by engineers and researchers interested in
the design, stability, safety, and performance of highway structures under
all combinations of geographical and
The Bridge Aerodynamics Laboratory is the only wind tunnel facility in the United States that is dedicated solely to the study of wind effects on transportation structures. It has the longest continuous history of exploring bridge aerodynamics to ensure the performance and safety of long-span bridges in strong winds and to advance our understanding of wind effects on transportation structures. The laboratory is federally owned and is staffed by a team of experienced scientists and engineers in the areas of structural engineering, aerodynamics, experimental methods, computational fluid dynamics, and wind engineering. The laboratory is a federally owned and federally funded research laboratory staffed under contract under the leadership of a senior federal engineer.

The
primary purpose of the laboratory is to evaluate new designs, investigate
performance problems of in-service structures, develop effective retrofit
solutions, establish the aerodynamic properties of structures and structural
components, support the development of new design guides and specifications,
develop more effective experimental procedures and simulation methods
and explore fundamental wind engineering problems.
