History:





NY 100's original southern terminus was in Yonkers, but was extended south through The Bronx and into Manhattan in 1934. When the Major Deegan Expressway (I-87) was built and opened in 1956, NY 100 was truncated back to its original southern end.

At the north end, NY 100 swapped its alignment with NY 118 in 1939 and was extended north to Croton Falls. The northern terminus would be moved to its current location around 1990.
