Interstate 390

Interstate 390 is an Interstate Highway in the western portion of the State of New York connecting the Southern Tier and the Finger Lakes to the metropolitan area of Rochester. The route serves as a primary north–south artery for commuters, commercial traffic, and regional travel between Interstate 86, U.S. Route 20, and the New York State Thruway. It passes through or near multiple municipalities and institutions, linking Corning, Avon, Geneseo, and suburbs of Rochester.

Route description

Interstate 390 begins in the vicinity of Corning near the interchange with Interstate 86 and New York State Route 17, proceeding northward through rural areas adjacent to the Finger Lakes National Forest and crossing near Keuka Lake. The highway traverses the towns of Bath, Avon, and Geneseo, providing access to institutions such as State University of New York at Geneseo and commercial centers in Avon. North of Geneseo, the route enters Monroe County, serving suburbs like Henrietta and connecting with major corridors including U.S. Route 20A and New York State Route 383. Approaching Rochester, the freeway meets Interstate 490 and provides links to Greater Rochester International Airport via adjacent arterials and to downtown Rochester by feeder expressways.

History

Plans for a limited-access route linking the Southern Tier and the Rochester area were developed during the expansion of the Interstate Highway System in the mid-20th century, with design studies involving agencies like the New York State Department of Transportation and regional planners from the Genesee Transportation Council. Construction proceeded in segments through the 1960s and 1970s; early sections opened connecting Corning to communities northward, while later work completed the northern approach into Rochester and connections with Interstate 490. The designation was applied in the 1970s, aligning with federal Interstate standards mandated by the Federal-Aid Highway Act of 1956. Subsequent upgrades have included interchange reconstructions near Avon and pavement rehabilitation projects coordinated with county and state agencies, reflecting evolving traffic patterns influenced by employers such as Corning Incorporated and institutions like RIT and University of Rochester.

Exit list

The route's exits provide access to a mix of state routes, county roads, and municipal streets serving population centers and attractions. Key interchanges include connections with Interstate 86/New York State Route 17 near Corning, interchanges serving Avon and Geneseo with links to New York State Route 36 and New York State Route 63, and northern termini interfacing with Interstate 490 and arterial routes into Rochester. Additional exits provide access to industrial parks near Henrietta, recreational sites around the Finger Lakes, and connection points for U.S. Route 20A and New York State Route 15. Mile-based control cities and exit numbering follow standards used statewide by the New York State Department of Transportation.

Traffic and usage

Traffic volumes vary considerably along the corridor, with lower average daily traffic in the Southern Tier and Finger Lakes segments near Corning and higher volumes approaching Rochester and suburban employment centers such as Henrietta and Brighton. Commercial vehicle proportions reflect regional freight patterns tied to manufacturers like Corning Incorporated and distribution facilities serving the Rochester metropolitan area. Seasonal tourism to the Finger Lakes and events at institutions including SUNY Geneseo and RIT cause periodic peaks. Traffic management strategies have involved coordination among the New York State Department of Transportation, regional transit providers like the Rochester Genesee Regional Transportation Authority, and local law enforcement for incident response and congestion mitigation.

Future plans and improvements

Planned and proposed improvements have emphasized interchange modernization, pavement rehabilitation, and multimodal access enhancements coordinated with regional planning bodies such as the Genesee Transportation Council and state capital program initiatives. Projects under consideration include targeted bridge replacements, widening of auxiliary lanes near high-demand interchanges serving Henrietta and Rochester suburbs, and upgrades to signage and intelligent transportation systems promoted by the New York State Department of Transportation to improve safety and freight mobility. Local municipalities have also discussed land-use and access management measures to balance growth around interchanges near Avon and Geneseo.
