NY 198 (Scajaquada Expressway)

NY 198 (Scajaquada Expressway) is a short state highway in New York connecting central Buffalo with the Town of Cheektowaga and providing access to major routes near Buffalo Niagara International Airport. The route traverses urban neighborhoods, parkland, and institutional corridors, and has been the focus of multiagency planning, environmental review, and community advocacy. It plays a strategic role in regional mobility, linking to the New York State Thruway, Interstate 90, and federal interstate routes.

Route description

NY 198 begins at a directional interchange with I-190 near the Buffalo River waterfront and the Canalside redevelopment area, then proceeds eastward as an at-grade limited-access roadway adjacent to LaSalle Park, Martin Luther King Jr. Park, and the Scajaquada Creek corridor. The alignment passes close to cultural and institutional landmarks including the Albright-Knox Art Gallery, the Buffalo History Museum, Delaware Park, the Baird Point Cultural Center, and the University at Buffalo South Campus. Interchanges and ramps serve NY 5, Porter Avenue, and arterial streets that provide access to the Allentown neighborhood, Elmwood Village, and commercial districts near Main Street. Eastbound traffic continues past parkland associated with the Olmsted Parks and Parkways system before terminating near Eggertsville and the Cheektowaga border, with connections toward I-90 and the Buffalo Niagara International Airport complex.

History

Conceived in postwar planning influenced by Robert Moses, the roadway was developed during mid-20th-century highway expansion tied to regional plans promoted by NYSDOT predecessors and local agencies. Initial construction intersected landscape designed by Frederick Law Olmsted and was controversial among advocates for the Olmsted Park System preservation, historic preservationists, and neighborhood groups such as the Allentown Association. During the 1960s and 1970s the expressway was integrated into Buffalo’s freeway network connecting to I-190, while later decades saw litigation and policy debate influenced by federal statutes including the National Environmental Policy Act and state-level review processes administered by NYSDEC and OPRHP. Civic responses involved organizations such as the Preservation League of New York State and local elected officials from the City of Buffalo Common Council and Erie County Legislature. Safety incidents and traffic studies prompted engineering updates under standards promulgated by the Federal Highway Administration and regional transportation planning by the Niagara Frontier Transportation Authority and the Governing Board of Metropolitan Transportation Studies.

Exit list

The expressway includes interchanges and ramps providing movements to and from several regional routes and local streets. Major interchanges connect to I-190, NY 5, Porter Avenue, and access roads serving the University at Buffalo, Buffalo State College, and cultural institutions such as the Buffalo and Erie County Botanical Gardens. Auxiliary ramps link to service roads near Elmwood Avenue and to arterial collectors serving Kensington corridors. Design configurations include directional ramps, partial cloverleaf elements, and signalized termini where the limited-access facility transitions to surface streets governed by county maintenance agreements.

Traffic and safety

Traffic volumes have reflected regional commuting patterns between Buffalo neighborhoods and suburban employment centers near Cheektowaga and Hamburg, generating peak-period congestion and collision clusters documented in NYSDOT crash data and local law enforcement reports from the Buffalo Police Department. Safety concerns intensified after high-profile incidents, prompting involvement by the National Transportation Safety Board in procedural review contexts and leading to targeted countermeasures consistent with Manual on Uniform Traffic Control Devices standards. Multimodal advocacy from groups including Walk Bike Buffalo, Buffalo Niagara Riverkeeper, and the Trust for Public Land has highlighted pedestrian, bicycle, and ecological hazards along the Scajaquada Creek crossing and within the Delaware Park corridor.

Reconstruction and redesign plans

A sequence of feasibility studies, environmental impact statements, and community charrettes initiated by NYSDOT in coordination with the City of Buffalo, Erie County, and federal funding partners examined alternatives ranging from preservation of the limited-access alignment to conversion to a surface boulevard. Stakeholders involved in planning included the National Park Service owing to the Olmsted legacy, the NYSDEC, the Federal Highway Administration, and nonprofit organizations such as the Olmsted Conservancy. Proposals evaluated scenarios for restoring park connectivity, enhancing stormwater management for the Scajaquada Creek watershed, and improving transit flow with protected bike lanes and pedestrian bridges consistent with guidance from the American Association of State Highway and Transportation Officials and the Institute of Transportation Engineers. Funding mechanisms considered capital allocations through Congestion Mitigation and Air Quality Improvement Program grants and state transportation capital programs. Community-selected alternatives emphasized context-sensitive solutions to reconcile mobility demands with restoration of historic landscape character.

Major intersections and connections

Key connections serve regional mobility: the junction with I-190 links to the Buffalo–Niagara Falls metropolitan area and cross-border corridors toward Niagara Falls and Fort Erie, Ontario; links toward I-90 and the New York State Thruway provide long-distance access toward Rochester, Syracuse, and Albany; arterial tie-ins facilitate movements to the Buffalo Niagara International Airport and freight routes serving the Port of Buffalo and rail yards operated by CSX Transportation and Norfolk Southern Railway. The expressway interfaces with urban corridors leading to cultural destinations such as the Albright-Knox Art Gallery, Kleinhans Music Hall, and institutional nodes including the Roswell Park Comprehensive Cancer Center and the University at Buffalo.
