摘要

The 20th century represented a dramatic evolution in steel bridge technology. The first half of that century featured some of the most spectacular bridges of our time, as many of the major physical obstacles to transporting people and goods were spanned. The second half of mat century featured another dramatic evolution of our highway system as the population expanded and the automobile became a way of life. In 1956, Congress passed legislation that gave birth to our country's Interstate highway system (MS). Thus began the building of an expansive highway network and its many bridges, linking primary urban centers. Through this period, evolution in design codes, bridge types, materials and construction methods was amazing. This paper chronicles some of the highlights in this evolution in the history of steel bridges and concludes with a brief look forward.
