 On April 1, 1980, ownership and maintenance of Williams Road (CR 70), a local east–west highway linking US 4 to Winter Street Extension, was transferred from Rensselaer County to the state of New York as part of a highway maintenance swap between the two levels of government.The new state highway became a westward extension of NY 136.In between Williams Road and Whiteview Road, NY 136 initially used a small portion of Winter Street Extension, which had been NY 405 prior to the swap.
