New York State Route 390 is a limited-access highway in Monroe County, New York, serving as a north–south connector between the city of Rochester and suburban communities near Lake Ontario and Charlotte. The route provides links to regional facilities including Monroe County Airport, the University of Rochester, and multiple state and interstate highways such as Interstate 490, Interstate 390, and New York State Route 104. It forms part of the arterial network that connects downtown Rochester with the towns of Brighton, Irondequoit, and Greece.
The corridor begins near the interchange with Interstate 490 and New York State Route 590 southeast of Rochester and proceeds north as a freeway paralleling local thoroughfares such as Lyell Avenue and Clinton Avenue. Within its southern segment the route provides access to facilities associated with University of Rochester Medical Center and the Rochester Institute of Technology commuter routes, and interchanges with New York State Route 31F and New York State Route 31. Traveling northward, it crosses the Genesee River corridor and serves the Charlotte-Genesee Lighthouse vicinity before intersecting with New York State Route 18 and terminating near Lake Ontario State Park at an interchange with New York State Route 104 in Greece. Along its alignment the highway traverses municipal boundaries of Rochester, Brighton, Irondequoit, and Greece, and interfaces with transit services provided by the Regional Transit Service.
The route developed from mid-20th century planning efforts tied to postwar suburbanization and federal highway policy exemplified by the Federal-Aid Highway Act of 1956. Early alignments were influenced by preexisting corridors serving Rochester industrial districts and port facilities on Lake Ontario, with staged construction during the 1960s and 1970s that reflected priorities of the New York State Department of Transportation and regional planners from Monroe County. Design and construction phases were coordinated with projects such as the expansion of Interstate 390 and upgrades to Interstate 490; the project later integrated standards emerging from the American Association of State Highway and Transportation Officials. Local controversies paralleled those in other metropolitan areas, invoking stakeholders including the Rochester City Council, Monroe County Legislature, neighborhood associations, and business groups centered in Rochester Business Alliance and downtown civic interests. Incremental improvements have followed, tying the corridor to statewide programs like the New York State Thruway Authority initiatives and regional economic development plans linked to entities such as Greater Rochester Enterprise.
The freeway includes interchanges with multiple principal routes that connect to statewide and interstate networks. Key junctions include its southern connection to Interstate 490 near central Rochester, an interchange with New York State Route 31 that provides access toward Brockport and Palmyra, a node linking to New York State Route 104 that serves corridors toward Sodus Point and Oswego, and connections facilitating movements to Interstate 390 and New York State Route 590. The interchange complexes interface with local arterials that lead to commercial centers such as Eastview Mall-area corridors and employment hubs proximate to the Rochester Technology Park and hospital campuses including Strong Memorial Hospital.
Planned projects affecting the corridor are coordinated by the New York State Department of Transportation in partnership with regional agencies such as the Monroe County Department of Transportation and metropolitan planning organizations like the Genesee Transportation Council. Improvement programs emphasize rehabilitation of pavement and bridges listed in state inventories, interchange modernization consistent with Manual on Uniform Traffic Control Devices guidelines, and multimodal integration supporting Amtrak-served corridors and local transit connections with RTS. Proposals under consideration have included ramp reconfigurations to enhance access to Monroe Community Hospital and expansions to accommodate freight movements tied to the Port of Rochester and logistics centers used by firms such as Xerox and distributors serving the Greater Rochester International Airport catchment. Funding mechanisms draw on state transportation bonds, federal grants administered through the United States Department of Transportation, and regional capital programs.
Traffic volumes reflect commuter flows between Rochester and suburban municipalities, with peak-period congestion concentrated near interchanges serving major employment centers like the University of Rochester and healthcare complexes including Rochester Regional Health. Freight usage links to distribution nodes and the Port of Rochester, while seasonal travel patterns increase during recreational access to Lake Ontario beaches and attractions in Charlotte. Data collected by the New York State Department of Transportation inform operational strategies such as incident management coordinated with New York State Police and local agencies including the Rochester Police Department and Monroe County Sheriff’s Office. Ongoing monitoring addresses safety metrics promoted by statewide initiatives like the Move Over Law and federal highway safety programs.
