New York State Route 15A
Encyclopedia
New York State Route 15A (NY 15A) is a north–south state highway
located in the western portion of New York
in the United States. It serves as an easterly alternate route of NY 15
, beginning in the Livingston County
town of Springwater
and ending 35.19 miles (56.63 km) to the north in the Monroe County
city of Rochester
. NY 15A meets U.S. Route 20A
(US 20A) in the hamlet of Hemlock, US 20
and NY 5
in the village of Lima
, and Interstate 390 (I-390) twice in Henrietta
and Brighton
. Its southern and middle sections traverse mostly rural areas, while the northernmost piece in Henrietta, Brighton, and Rochester passes through significantly more developed areas.
From 1927 to the late 1930s, modern NY 15
was part of NY 2. As a result, all of what is now NY 15A was originally designated as New York State Route 2A as part of the 1930 renumbering of state highways in New York. Two parts of the route were sub-standard at the time; however, those sections were rebuilt in the early and mid-1930s. NY 2 was supplanted by an extended US 15
ca. 1939, at which time NY 2A was renumbered to NY 15A to match its parent's new designation.
in the Springwater
hamlet of the same name, located on the east side of a large valley in southeastern Livingston County
. The route heads northward as North Main Street, proceeding along the eastern base of the valley as it passes through the northern half of the community. Outside of the hamlet, NY 15A enters a rural, undeveloped area dominated by dense forests to the east and a low-lying, slightly more open area to the west. As the route approaches the Livingston–Ontario
county line, the lowlands give way to marshes, which in turn lead to Hemlock Lake
at the county line. While in Ontario County, NY 15A follows a more inland route to the east, passing through an isolated forest situated between Hemlock and Canadice Lake
s. After 6 miles (10 km), the highway reenters Livingston County near the northern end of Hemlock Lake.
Now in the town of Livonia
, NY 15A becomes Bald Hill Road as it passes by Hemlock Lake Park, a local park situated at the northeastern tip of the lake. It changes names again just 1.5 miles (2.4 km) later upon entering the hamlet of Hemlock. Here, it becomes Main Street and intersects US 20A
, which forms a concurrency
with NY 15A along the length of Main Street. The concurrency continues through Hemlock and into rural Livonia, where the 2 miles (3.2 km) overlap ends as US 20A turns west towards Buffalo
. NY 15A, meanwhile, heads northward into the town of Lima
as Plank Road. It continues across rural terrain for another 3 miles (5 km) to the village of Lima
, where it becomes Lake Avenue. At the village center, NY 15A crosses over US 20
and NY 5
and changes names to Rochester Street. The route leaves the community and its residential surroundings after 0.75 miles (1.21 km), but retains the Rochester Street name until it reaches the Livingston–Monroe
county line west of Honeoye Falls
.
, NY 15A takes on the name Rush–Lima Road and begins curving to the northwest. It connects to Honeoye Falls twice: first via Main Street at a junction just north of the county line, and later by way of Monroe Street (formerly NY 363) at an intersection 1 miles (1.6 km) to the northwest. Past Monroe Street, the route makes a long, significant turn to the west, following Honeoye Creek
into the town of Rush
and the hamlet of the same name. The highway meets Rush – West Rush Road at an intersection south of the community, at which point NY 15A turns back to the north and crosses over Honeoye Creek. In the process, NY 15A becomes East Henrietta Road, a name the highway retains until its northern end in Rochester
. On the opposite side of the creek, NY 15A intersects NY 251
in the center of Rush.
Outside of Rush, NY 15A takes on a more northeasterly alignment as it passes Rush's town reservoir and enters the town of Henrietta
. The surroundings initially remain as rural as they were in Rush; however, the amount of development along the highway gradually increases as the route approaches and passes over the New York State Thruway
(I-90
). One mile (1.6 km) later, NY 15A intersects NY 253
in a densely populated area west of Rush-Henrietta Senior High School
. The homes continue for another 0.5 mile (0.80467 km) to the Monroe County Fairgrounds (home to The Dome Center
), at which point NY 15A begins to become lined with commercial establishments. The trend temporarily ceases around an interchange with I-390
—where NY 15A curves northwestward—but resumes ahead of a junction with NY 252
, itself a major commercial strip.
North of NY 252, NY 15A passes under the CSX Transportation
-owned West Shore Subdivision
and crosses into Brighton
. Just past the town line, the route connects to Clay and Brighton–Henrietta Town Line Roads by way of a grade-separated intersection 0.25 mile (0.402335 km) north of the railroad overpass. It continues onward, passing along the west side of the sprawling Monroe Community College
campus to another interchange with I-390. NY 15A passes over the Erie Canal
and enters the city of Rochester shortly afterward. Once in the city, the route passes by two large office campuses south of Westfall Road and several blocks of homes north of the street before merging back into NY 15 (Mount Hope Avenue) at a junction east of Strong Memorial Hospital
.
was originally designated as part of NY 4 when the first set of posted routes in New York
were assigned in 1924. The route was renumbered to NY 2 in 1927 to eliminate numerical duplication with the new US 4
in eastern New York. Modern NY 15A, meanwhile, was only partially state-maintained by the mid-1920s. In 1926, only two sections of the route were state-owned: from Monroe Street west of Honeoye Falls
north to Rochester
, and the segment of highway in Livonia
that modern NY 15A shares with US 20A
. In spite of this fact, all of what is now NY 15A was designated as NY 2A, an alternate route of NY 2 between Springwater
and Rochester, in the 1930 renumbering of state highways in New York.
The sub-standard sections of the route between Springwater and Hemlock and from north of Hemlock to Honeoye Falls were improved in stages over the next half-decade, beginning with the piece between the villages of Lima
and Honeoye Falls ca. 1931. The remainder of the Hemlock – Honeoye Falls segment and the entirety of the route south of Hemlock was rebuilt ca. 1934. Ca. 1939, NY 2 was replaced by US 15
, which was extended northward from its previous terminus at the Pennsylvania state line to Rochester. NY 2A was renumbered to NY 15A as a result. NY 15A has not been substantially altered since that time.
