NY 383 begins at an intersection with
NY 36 in the
hamlet of
Mumford, located just north of the border between
Monroe and
Livingston Counties in the town of
Wheatland. Taking on the name Scottsville–Mumford Road, NY 383 follows
Oatka Creek east through open fields and passes through the small hamlet of
Garbutt on its way to the village of
Scottsville, where it becomes Caledonia Avenue. At an intersection with the southern terminus of
NY 386, NY 383 turns east onto Main Street and follows it through the residential southern portion of the village and past the
Scottsville Free Library. Main Street comes to an end at a junction with River Road (
NY 251, which has its western terminus here) and Rochester Street near the northern bank of Oatka Creek. Here, NY 383 curves north onto Rochester Street and proceeds through eastern Scottsville. The street name of NY 383 becomes Scottsville Road upon intersecting the western terminus of
NY 253. Past this junction, the surroundings shift from village streets to housing tracts as the route exits Scottsville. North of the village, NY 383 re-enters open fields once again upon crossing the Wheatland–
Chili town line. in
Rochester, shown here, is located adjacent to the
Blue Cross Arena Within Chili, NY 383 parallels the path of the
Genesee River, which Oatka Creek feeds into east of the village of Scottsville. During this stretch, the route passes under the
New York State Thruway (
Interstate 90 or I-90) and intersects Mile Wood Road, a highway connecting NY 383 to Mile of Woods, a hamlet on the west bank of the Genesee River. From this point, NY 383 heads to the north while the river flows to the northwest toward the route. Upon meeting the waterway, NY 383 begins to run along the Genesee River's western bank to a junction with
NY 252. It continues along the riverbank as it proceeds northward, passing over
Black Creek and
crossing the
West Shore Subdivision, a rail line owned by
CSX Transportation. As NY 383 approaches the
Greater Rochester International Airport, it diverges from the river and has a junction with Paul Road (unsigned
County Route 168 and formerly
NY 252A) south of the Airport. NY 383 follows the southern edge of the airport to an interchange with
I-390 at exit 17. Shortly afterward, NY 383 crosses the
Erie Canal and enters the city of
Rochester. At this point, maintenance of NY 383 shifts from the
New York State Department of Transportation to the city of Rochester. Scottsville Road continues within the city for four blocks to a three-way junction with Genesee Street and Elmwood Avenue. NY 383 veers north onto Genesee Street for six blocks to Brooks Avenue. Here, the route turns east to access South Plymouth Avenue. NY 383 continues north on Plymouth Avenue through densely populated sections of the city to Ford Street. The route curves east to follow Ford for one block to Exchange Boulevard, where it turns back to the north toward downtown Rochester. NY 383 follows Exchange Boulevard along the Genesee River's west bank and under the
Frederick Douglass–Susan B. Anthony Memorial Bridge, which carries
I-490 over both NY 383 and the river. Past the bridge, the highway enters downtown, where it passes the City of Rochester Public Safety Building and the
Blue Cross Arena before terminating at a junction with East Broad Street (
NY 31). ==History==
