"In Crossing the Hudson, Donald Wolf shows with a fine eye for detail how the engineering accomplishments embodied in bridges and tunnels are inseparably linked to the larger social and political context in which they are conceived and built. This extremely well written book not only provides revealing insights into the history of the Hudson River, its environs, and their people and infrastructure, but also demonstrates in case after case how interesting the stories surrounding them can be." - Henry Petroski (author of Engineers of Dreams) "A beautifully written, richly researched and illustrated text even a commuter can admire." (Star-Ledger) "Engineers and history buffs alike will take a shine to Donald E. Wolf's Crossing the Hudson. Thoroughly researched and written in an authoritative but lively style, this tome tackles an aspect of the Valley's past." (Hudson Valley Magazine) "In Crossing the Hudson, retired civil engineer Donald Wolf chronicles a different, less documented history of the Hudson: two centuries of bridge and tunnel building. The book is a blend of American history and civil engineering history, with a dash of biography. It is a book for quiet enjoyment, a mellow cruise down the Hudson and through American history." (Civil Engineering) "A fascinating look at the history of the many Hudson River bridges and tunnels. This work is a must read for anyone interested in structural engineering, bridges, and the history of engineering. Highly recommended." (Choice) "This is a well-researched, beautifully written history of the 21 bridges and tunnels that cross the Hudson between the Capital Region and New York City. [Wolf's] deep knowledge of the Hudson valley brings to life the social and historical backgrounds for each crossing."(Daily Gazette)
