Pittsburgh's Bridges

Résumé du livre

This book's quarto landscape format enables the many illustrations to be printed in fine detail. Almost all are historic photo images gleaned from the files of state, county and city engineering and design bureaus. These were originally done for record purposes to document newly built structures. Several pages are devoted to each selected major structure. Yet this is more than a picture book. The author. due to his long experience with such work, is able to succintly discuss each selected structure and its history.
