Donald E. Wolf, \"Crossing The Hudson: Historic Bridges and Tunnels of the River\"
Publisher: Riv...erg...ate | 2010 | ISBN: 0813547083 | PDF | 288 pages | 2 MB

Fog, tide, ice, and human error--before the American Revolution those who ventured to cross the vast Hudson Valley waterway did so on ferryboats powered by humans, animals, and even fierce winds. Before that war, not a single Hudson River bridge or tunnel had been built. It wasn't until Americans looked to the land in the fight for independence that the importance of crossing the river efficiently became a subject of serious interest, especially militarily. Later, the needs of a new transportation system became critical--when steam railroads first rolled along there was no practical way to get them across the water without bridges.
