Interstate 390 (New York) is an Interstate Highway running north–south in western New York, connecting the Southern Tier and Finger Lakes regions to the Rochester metropolitan area and the New York State Thruway. The route serves as a spur from I‑90 and links with I‑86 and NY 390 continuations, providing access to Genesee Valley Park, Buffalo, and regional facilities including Greater Rochester International Airport, University of Rochester, and Rochester Institute of Technology.

Route description

Interstate 390 begins at a junction with I‑86 and NY 15 in Avon, running north through Livonia and alongside Canandaigua Lake excursion corridors toward Pittsford and Brighton. The freeway parallels NY 15A and intersects US 20 and NY 5 as it approaches the Rochester urban area, providing access to Mount Hope Cemetery and Highland Park. Northbound, the route crosses the Genesee River corridor and interfaces with I‑490 and NY 31F, before terminating at a semi-directional interchange with I‑90 near Le Roy and Batavia. The corridor serves freight movements to Port of Rochester access points and links to regional rail hubs such as Rochester Station.

History

Planning for the freeway system that produced the highway traces to mid-20th-century regional studies influenced by Robert Moses-era infrastructure models and federal Federal-Aid Highway Act of 1956 funding, with routing adjusted to serve population centers including Hornell and Canandaigua. Initial construction segments opened during the 1960s and 1970s, coordinated by the New York State Department of Transportation and the Federal Highway Administration. Designation as an Interstate spur followed standards promulgated by the AASHTO and led to integration with the Interstate Highway System grid. Subsequent decades saw upgrades related to safety recommendations from the National Highway Traffic Safety Administration and rehabilitation projects tied to stimulus programs such as the American Recovery and Reinvestment Act of 2009. Local controversies over alignments involved stakeholders including Monroe County officials, advocacy groups like Rails-to-Trails Conservancy, and preservationists concerned with sites near Susan B. Anthony House.

Exit list

The freeway includes exits that connect to principal routes and municipalities: southern termini at I‑86/NY 15 in Avon; interchanges with US 20, NY 96 in Victor; a major junction with I‑490 for Downtown Rochester access; and northern termini at I‑90 near Le Roy. Auxiliary ramps serve industrial parks linked to Excellus BlueCross BlueShield campuses and academic institutions such as University of Rochester and Rochester Institute of Technology. Mileposts and exit numbers conform to New York's mileage-based system, with rest areas and truck parking located near Holley and rural interchanges.

Auxiliary routes

The corridor is complemented by NY 390, which extends the expressway toward Irondequoit and the lakeshore, and by spur connections that include service roads into Perinton and industrial access ramps serving Rochester Technology Park. Regional planning documents reference potential linkages to I‑490 auxiliaries and municipal arterials in Monroe County that provide distribution to Brighton, Greece, and Webster. Coordination with New York State Thruway Authority ensures continuity of route numbering and interchange design for connections to I‑90.

Traffic and tolls

Traffic volumes on the route vary from commuter peaks near Rochester to lower rural counts near Avon. The highway supports commuter flows serving employers such as Eastman Kodak Company, Paychex, and medical centers including Strong Memorial Hospital. Freight traffic links to Conrail and CSX Transportation-served yards and to regional warehousing near Holcomb. The route itself is untolled, with tolling applicable only where motorists connect to the Thruway on I‑90, administered by the New York State Thruway Authority. Traffic management leverages ITS deployments similar to those used on I‑81 and coordination with New York State Police for incident response.

Future plans and improvements

Planned improvements emphasize bridge rehabilitation, pavement preservation, and interchange modernization funded through state transportation plans and federal aid including programs overseen by the Federal Highway Administration. Proposals under discussion include capacity enhancements near Victor to serve Eastview Mall area growth, reconstruction of legacy interchanges to meet AASHTO design criteria, and multimodal integration with Greater Rochester International Airport access improvements. Environmental reviews reference standards from the New York State Department of Environmental Conservation and community input from Monroe County public workshops. Long-range scenarios consider potential corridor resiliency measures related to climate impacts identified by regional planning agencies such as the Genesee Transportation Council.
