New York State Route 173

New York State Route 173 is an east–west state highway traversing central New York between Syracuse and Cazenovia, passing through suburban Liverpool, industrial Syracuse Hancock International Airport area environs, and rural communities near Chittenango. The route connects with major corridors including Interstate 81, NY 5, and NY 13, serving commuter, commercial, and agricultural traffic between Onondaga County and Madison County.

Route description

The western terminus lies in Syracuse near junctions with Interstate 81 and NY 5, proceeding east through mixed residential neighborhoods adjacent to Syracuse University, Onondaga Community College, and industrial areas near New York Central Railroad rights-of-way. Eastbound segments traverse commercial corridors near Liverpool and cross waterways associated with Onondaga Lake and tributaries feeding into Seneca River and Erie Canal systems, linking to NY 690 and providing access toward Syracuse Hancock International Airport via collector roads. Further east the highway passes through suburban and exurban zones adjacent to Manlius and rural landscapes characterized by fields and woodlands near Chittenango Falls State Park, intersecting regional routes such as NY 91 and NY 92 before terminating near Cazenovia Lake and Cazenovia where connections to US 20 and NY 13 facilitate travel toward Ithaca and Utica.

History

The corridor originated as local turnpikes and county roads in the 19th century serving Erie Canal commerce and farm-to-market movement linking Onondaga County towns such as Syracuse and Manlius with Madison County hamlets including Chittenango and Cazenovia. Early 20th-century improvements coincided with statewide initiatives led by figures such as George W. Perkins and agencies antecedent to the New York State Department of Transportation that formalized alignments now paralleling historic rail lines operated by companies like New York Central Railroad and Lehigh Valley Railroad. The route received its numeric designation during statewide renumbering efforts contemporaneous with the establishment of US 20 and NY 5, adapting to automobile-era needs and reflecting shifts from toll pikes to public highways championed by Progressive Era planners associated with municipal authorities in Syracuse and county boards in Onondaga County. Mid-20th-century widening projects connected the highway to interstates such as Interstate 81 and facilitated suburbanization around Syracuse Hancock International Airport, with later rehabilitation funded through state capital programs influenced by federal acts like the Federal Aid Highway Act of 1956.

Major intersections

The corridor intersects multiple state and federal routes including junctions with Interstate 81 near Syracuse, NY 5 along urban arterials, NY 690 serving the Liverpool area, NY 31 and NY 48 in northern Onondaga County, and eastern connections to NY 13 and US 20 in the vicinity of Cazenovia and Canastota, with auxiliary links to county routes administered by Onondaga County Department of Transportation and Madison County Department of Public Works.

Traffic and usage

Traffic volumes vary from urban peak flows near Syracuse and commercial nodes in Liverpool—where counts reflect commuter patterns to employment centers such as SUNY Upstate Medical University and industrial parks—to lower rural counts east of Manlius and around Chittenango tied to agricultural transport and seasonal tourism to destinations like Chittenango Falls State Park and Cazenovia Lake. Freight movements utilize the route for last-mile distribution linking to regional terminals formerly served by New York Central Railroad and contemporary trucking routes to hubs in Syracuse Hancock International Airport and the Port of Oswego via connecting highways. Safety and congestion metrics have prompted studies by New York State Department of Transportation in cooperation with Onondaga County planners, metropolitan analyses from the Syracuse MPO, and environmental reviews tied to New York State Environmental Quality Review Act processes.

Future developments and improvements

Planned improvements include intersection upgrades, pavement rehabilitation, and corridor safety enhancements proposed by New York State Department of Transportation and local governments in Syracuse, Liverpool, and Manlius to address growth related to employment centers such as SUNY Upstate Medical University and expansion near Syracuse Hancock International Airport. Proposals consider multimodal access improvements connecting to transit providers including Centro services and bicycle-pedestrian projects endorsed by regional advocacy groups and the Federal Highway Administration's grant programs, with funding discussions involving New York State Assembly representatives and New York State Senate committees overseeing transportation capital budgets. Environmental permitting and community consultations reference conservation interests around Chittenango Falls State Park, Cazenovia Lake, and tributary waters feeding the Erie Canal system.
