On March 20, 1801, an act was passed authorizing the building of a new turnpike road from the Hudson River to the Delaware through what was then Ulster and Orange counties. There were two important reasons for this undertaking. One was to facilitate travel between Newburgh and the rich coalfields of Pennsylvania and the other was to provide a suitable passage for large droves of cattle and wood products taken from the virgin forests of Sullivan County. The proposed Newburgh and Cochecton Turnpike ultimately brought about the founding of the village of Monticello.
