  • Abstract:
    As the Nation's highway infrastructure continues to deteriorate, bridge deficiencies adversely impact mobility, safety, and economic development. Many State departments of transportation (DOT) are struggling to maintain an acceptable schedule of bridge maintenance, repair, and replacement. In 2002, 14 percent of all bridges that were 6.1 meters (20 feet) or longer were considered structurally deficient. Restrictions on vehicle weights that result from these deficiencies may lead to certain vehicles using alternate routes, thus lengthening travel times and reducing efficiency. At the same time, traffic congestion continues to increase. To mitigate the problems associated with deficient bridges and increased traffic, bridges throughout the country must be replaced or widened, with lane capacity added. Improving the Nation's infrastructure will require a significant investment. To mitigate congestion, construction schedules must be accelerated to reduce the impact on the public, while observing economic stringencies to conserve funds for other projects. To achieve these goals, transportation practitioners responsible for foundation design and construction must identify more efficient and cost-effective methods for supporting structures.
