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. 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. The NYSDOT began a multi-year project in 2017, to upgrade the western terminus of NY-531 at NY-36, and to expand and improve a three mile corridor of NY-31 from Adams Basin west to the Sweden town line. The work is intended to improve capacity and safety of the busy main corridor from Brockport to the city of
