Six Bridges

"Ammann's long-span bridges came to define an epoch and shape the modern New York metropolis. This book is the first to examine the genius of Ammann and the special group of bridges he designed and engineered as part of the New York region's interstate highway system. With more than 200 archival photographs, the book vividly displays the physical transformation of New York, the development of long-span suspension structures, the construction process of each bridge, and the spectacular completed bridges."--BOOK JACKET.
