Input: Question: Who proposed the legislative routes? Passage:In 1908, the New York State Legislature created a statewide system of unsigned legislative routes. The portion of what is now NY34 from Van Etten to Ithaca was included in Route9, which originally began in Horseheads and went generally northeast across central New York to Bouckville. North of Ithaca, two sections of modern NY34from Cayuga Heights Road north to current NY34B in Lansing and from the north end of NY34B in Fleming to Auburnbecame part of Route11. On March1, 1921, Route9 was realigned south of Van Etten to follow modern NY34 south to Chemung Street in Waverly. When the first set of posted routes in New York were assigned in 1924, none of modern NY34 received a signed designation except for the current overlap between NY34 and NY13 south of Ithaca, which became NY13 at this time.
