Originally, Cohoes Crescent Road may have been a foot path beside the south bank of the Mohawk River between the Hudson River and points west and used for centuries by Native Americans. The Native Americans knew places where the river was shallow and safe enough most times of the year to cross sides by fording through only a couple feet of water. Eventually early Europeans settled along both banks of the Mohawk River above the Cohoes Falls and used these same fording points as well.
When the original Erie Canal was completed in 1825, a series of sixteen locks were needed between the Erie Canal basin at Albany and the canal aqueduct spanning the Mohawk River at Crescent in order to rise above the height and natural barrier of the Cohoes Falls. Known as the “Terrible Sixteen’s” as it took an entire day for a boat to pass through them all. Once above the falls, the Erie Canal wound its way along the southern bank of the Mohawk to the Crescent aqueduct where it crossed into what is now Saratoga County slightly east of where State Rt. 9 crosses today. The canal here was formed and protected by an earthen berm separating and protecting the canal bed from the waters and winter ice of the adjoining Mohawk River.
This berm doubled as the towpath between the lock at the top of the falls to the aqueduct structure at Crescent which also supported a wagon bridge connecting both sides of the Mohawk. Being slightly longer than two miles in length, the berm eventually became known as the Cohoes Crescent Road. Early stages used this route to travel between Cohoes and points north in Saratoga County.
The Erie Canal here was abandoned by the State of New York with the construction of the new, New York State Barge Canal System of the early 20th Century. Large concrete dams were built here at Crescent raising the level of the river and obliterating the old river fords. The new Barge Canal locks at Waterford replaced the series of locks at Cohoes. The Mohawk River itself was now used by motorized canal boats. The road was eventually abandoned to the Town of Colonie. It became part of the Mohawk Towpath Scenic Byway in 2003.
