what is now NY 250 was originally taken over by the state of New York during the 1910s and 1920s. Work to improve the highway to state highway standards was performed in stages, beginning in the town of Webster and gradually heading south through Fairport to Perinton. The segment north of the Penfield–Webster town line was improved at a cost of just over $103,807 (equivalent to $ in ) and added to the state highway system on October 24, 1913. Construction on the next section between Liftbridge Lane in Fairport and the Penfield–Webster town line cost roughly $94,140 (equivalent to $ in ). It was accepted into the system on January 4, 1915. South of Fairport, the section from modern NY 31 north to the Fairport village line was added on January 19, 1916, following a nearly $17,127 (equivalent to $ in ) project to improve the road. Lastly, the portion south of modern NY 31 was added in the late 1920s. The four state-maintained segments were legislatively designated, but not signed, as State Highways 574, 574A, 1290, and 1836, respectively, for inventory purposes. The section of current NY 250 in Fairport between the southern village line and Liftbridge Lane was never taken over by the state and is village-maintained. Designation In 1908, the New York State Legislature created Route 20, an unsigned legislative route extending from Elbridge to Rochester via Fairport. Initially, Route 20 entered the village on High Street and followed Main Street south across the Erie Canal to Church Street, where it turned west toward Rochester. On March 1, 1921, Route 20 was realigned to enter Monroe County on modern NY 31. At the junction of Palmyra and Moseley Roads, Route 20 turned north, following SH 1290 into Fairport. It rejoined its original alignment at the junction of Church and Main Streets. None of SH 1290 received a signed designation when the first set of posted routes in New York were assigned in 1924. SH 1290 was not assigned a signed designation until the 1930 renumbering of state highways in New York when it became part of NY 250, a new route that extended south over SH 1836 to NY 15 (now NY 96) in Perinton and north over SH 574A and SH 574 to Lake Road in Webster. When NY 33B—the predecessor to NY 31F—was assigned , it entered Fairport on Church Street and turned north
