Transportation

Canals, Railroads, Philadelphia, and the Struggle for Internal Improvement in the Cumberland Valley, 1825-1837

In April 1825, the Pennsylvania General Assembly authorized the construction of the "Public Works," a state-built system of canals and railroads designed to provide improved transportation throughout the Commonwealth.  The most vital portion of the Public Works was the "Main Line," a 395-mile long series of canals and railroads built to link the state's largest city, Philadelphia, with the important western city of Pittsburgh.
