New York State Route 531 (NY 531) is a limited-access, east–west state highway located in Monroe County, New York, in the United States. The route extends for from the far northwestern suburbs of Rochester to the town of Gates located just west of the city. The western terminus of the route is at an intersection with NY 31 and NY 36 west of the village of Spencerport in the town of Ogden, while the eastern terminus of NY 531 is at Interstate 490 (I-490) exit 8 west of the Rochester city limits. NY 531 is the primary route between Rochester and the village of Brockport, located northwest of NY 531's west end. Route 531 is one of New York's only state highways with a speed limit of 65 mph. The expressway was constructed in three sections, the first of which opened in the 1960s as New York State Route 940P, an unsigned reference route, and extended from I-490 to Elmgrove Road. An extension of NY 940P to Manitou Road was completed in 1984, at which time the expressway was redesignated as NY 531. The final section between NY 36 and Manitou Road opened to traffic in 1995. NY 531 is officially designated the Senator Ralph Quattrociocchi Memorial Highway in honor of Ralph E. Quattrociocchi, a New York State Senator who played a large role in making the second extension of NY 531 possible. The road is also known as the Spencerport Expressway, named for the village near the highway's western terminus. In the mid-2000s, a number of grants were given by various agencies to the New York State Department of Transportation (NYSDOT) to finance research and planning for a potential extension of NY 531 westward to Redman Road in Brockport. A 2007 meeting between residents of Brockport and officials from NYSDOT revealed three options that were under consideration: an extension of NY 531 to Redman Road, the widening of NY 31 through the towns of Ogden and Sweden, and keeping the status quo. Ultimately, the first two options were ruled out in 2009, at which time NYSDOT announced only small-scale projects to alleviate areas of traffic congestion will be considered. ==Route description== Eastbound NY 531 begins at NY 31 a half-mile (0.8 km) west of the northern terminus of NY 36. NY 531 heads southeast from Brockport–Spencerport Road (NY 31), following a one-lane ramp east to NY 36. Shortly before intersecting with Washington Street (NY 36) at an at-grade intersection, the ramp widens to two lanes. At NY 36, NY 531 westbound terminates, forcing commuters to exit onto NY 36. Past the junction with NY 36, NY 531 becomes a four-lane limited-access highway, passing through open fields as it heads east through rural Ogden. Directly south of Spencerport, NY 531 encounters South Union Street (NY 259) by way of a diamond interchange bordered on both sides by small housing tracts. The roadway continues eastward, reentering open and mostly undeveloped areas of the town. It heads past farmland for before turning southward a short distance east of an overpass carrying Gillett Road. NY 531 proceeds due south for , passing over Lyell Road at the midpoint of the segment, before returning to an east–west alignment just ahead of the Manitou Road exit, where NY 531 crosses into the town of Gates.〔 Between Manitou Road and Elmgrove Road (NY 386), NY 531 is flanked on both sides by frontage roads in length. NY 531 eastbound connects to Manitou Road, NY 386, and the Rochester Tech Park solely by way of the south frontage road, designated NY 946E, while the north frontage road, designated NY 946F, acts as a collection road for the separate ramps to NY 386 and Manitou Road from NY 531 westbound. Both frontage road designations are unsigned reference routes;〔〔 in fact, reference markers along the two roads display "531" for the route number instead of their respective designations. The westbound exit to the Rochester Tech Park, a standalone two-lane ramp that splits from NY 531 a short distance west of the NY 386 overpass, has no connection to the north frontage road.〔 West of NY 386, the expressway expands to three lanes eastbound as it leaves the heavily commercialized and industrialized area around Elmgrove and Manitou Roads and enters a narrow, wooded area bordered by homes to the north. Not far to the east, NY 531 comes to an end at a slightly modified directional T interchange with I-490. Heading eastbound, the two leftmost lanes connect NY 531 to I-490 eastbound while the right lane links to I-490 westbound north of I-490's modified cloverleaf interchange with NY 33.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New York State Route 531」の詳細全文を読む スポンサード リンク
