New York State Route 312
New York State Route 312 is a short state highway connecting U.S. [Route 6 in New York|U.S. Route 6] and New York [State Route 22|NY 22] within the town of Southeast in Putnam County, New York. It allows indirect access to the village of Brewster from Interstate 84, and is often heavily used by local residents at rush hour in preference to the more complicated nearby access to I-684. The western terminus of the route is at US 6 roughly northwest of Brewster, and the eastern is in the hamlet of Sears Corners.
The designation NY 312 was originally assigned to what is now NY 164 as part of the 1930 [state highway renumbering (New York)|1930 renumbering of state highways in New York] before being shifted south to its current location in 1937.
Route description
NY 312 begins at US 6 in Southeast, New York just northeast of Middle Branch Reservoir, one of the many reservoirs in Putnam County which supply New York City's large need for drinking water. The route heads northeast, before veering to the north after a 0.5 mile to bypass a hill high. Past the hill, the route curves eastward then northeastward as it meets I-84 by way of an interchange and approaches the hamlet of Dykemans.In Dykemans, NY 312 serves the Metro-North Railroad's Southeast station, located on the railroad's Harlem Line. Just north of the station, NY 312 turns almost due east as it crosses the Harlem Line at-grade and exits Dykemans. from the railroad crossing, the route intersects North Brewster Road and Farm to Market Road in the hamlet of Brewster Hill. From here, it travels along the northern edge of Bog Brook Reservoir, another large reservoir which supplies drinking water to New York City. NY 312 proceeds east to the hamlet of Sears Corners, where it terminates at NY 22.
