ROADS AND BRIDGES: PAST, PRESENT, AND FUTURE

Our roads and bridges are major contributors to our social and economic well-being, but they also pose major concerns for our energy and environmental future. This article briefly reviews the physical condition and performance of the interstate highways and bridges in the U.S., concluding that our highway and bridge infrastructure is not performing up to the public's expectations. Attention is then focused on the future and what can be done now to improve our highway and bridge infrastructure. Areas discussed include traffic congestion, travel demand management, Intelligent Vehicle Highway Systems, the Strategic Highway Research Program, automobility, the four E's of our transportation future (Energy, Engineering, Environment, and Economics), and the President's national transportation policy.
