U.S. Route 219 in New York

US 219 crosses the New York–Pennsylvania border at Carrollton. The road begins by heading northward towards the Southern Tier Expressway, paralleling Tunungwant Creek.[5] Just after the Pennsylvania border, East Main Street becomes Hillside Drive and soon after Old U.S. Route 219 as it parallels US 219 for a short time. The road quickly merges into the current alignment as the U.S. route enters the hamlet of Limestone. A second incarnation of Old Route 219 parallels the U.S. route throughout Limestone. The road merges in just north of Limestone and US 219 continues northward. South Nine Mile Road (County Route 30 or CR 30) leaves to the right just before the road merges into the Southern Tier Expressway (I-86 and NY 17). Also present at this intersection is US 219 Business. The three roads overlap for six miles (10 km) until exit 21, where US 219 leaves the Southern Tier Expressway in Salamanca.[6]

US 219 crosses through the city of Salamanca and heads north towards Ellicottville.[6] While in Salamanca, US 219 and NY 417 become concurrent for about one mile (1.6 km). At the end of the concurrency comes the end of the business route. CR 49 terminates just north of Salamanca as US 219 enters Peth. In Peth, CR 67 leaves to the right. In Great Valley, NY 98 leaves to the north. US 219 enters Ellicottville and intersects with NY 242.[7] The two roads become concurrent for a short distance when US 219 turns to the north. Several Cattaraugus County roads intersect in the distance from Ellicottville to the Erie County border. The first is CR 75, the second is a concurrency between CR 53 and CR 85, and the third is CR 12, which has a brief concurrency with US 219 before leaving to the east.[8] After an intersection with CR 77, US 219 has a brief concurrency with CR 85 before it becomes a limited-access highway and crosses Cattaraugus Creek as it enters Erie County.[9]

US 219 is a freeway for its entire length in Erie County. About 2 miles (3 km) from the county line, US 219 connects to NY 39 at an interchange west of the village of Springville.[10] The highway continues to the northwest, connecting to CR 49 (Genesee Road) 3 miles (5 km) later and CR 233 (Rice Road) after another 6 miles (10 km). Five miles later, US 219 encounters NY 391 in Creekside.[11]

The route continues, connecting to CR 44 (New Armor Duells Road), a highway leading to NY 240 in the village of Orchard Park. Not far to the north is the next interchange with US 20A, which provides access to nearby New Era Field.[11] North of the village but still in the town of Orchard Park, US 219 crosses over US 20 prior to meeting NY 179 at an interchange just north of the US 20 overpass. The highway continues, curving to the northwest as it enters West Seneca and approaches the New York State Thruway (I-90). Instead of immediately merging with the Thruway, US 219 runs parallel to the Thruway for roughly 1 mile (1.6 km), with the northbound lanes running alongside the east side of the Thruway and the southbound lanes running alongside the west side. The two highways share an interchange with Ridge Road before US 219 finally merges into the Thruway.[11]

When the first set of posted routes in New York were assigned in 1924, NY 18 was assigned to an alignment extending from the Pennsylvania state line north of Bradford to downtown Buffalo. NY 18 went north from the state line to Bradford Junction, where it intersected NY 17 (now NY 417), another route assigned in 1924. The two routes converged here and overlapped each other northwest to Salamanca, where NY 17 continued westward toward Jamestown while NY 18 proceeded northwestward toward Little Valley. NY 18 originally connected to PA 6 at the state line;[12][13] however, by 1929, it connected to US 219 instead.[14] In the 1930 renumbering of state highways in New York, the highway connecting NY 17 and NY 18 in Salamanca to Great Valley was designated as part of NY 98.[15] Assigned at the same time was NY 62, a route extending from Great Valley to NY 18 in downtown Buffalo by way of Ellicottville, Ashford, Springville, and Hamburg.[16][17]

US 62 was extended into New York c. 1932; as a result, the portion of NY 62 south of Athol Springs was renumbered to NY 75 to eliminate numerical duplication with the new U.S. Highway. The remainder of old NY 62 became part of an extended NY 5.[18][19] US 219 was extended into New York c. 1935, overlapping NY 18, NY 98, and NY 75 northward to a junction with US 62 in Hamburg.[3][4] The overlap with NY 75 was eliminated by 1940 when NY 75 was truncated northward to US 62 in Hamburg.[20] The other two overlaps ceased to exist c. 1962 when NY 18 and NY 98 were truncated to Lewiston and Great Valley, respectively.[21][22]

When it was first extended into New York, US 219 continued north from Ellicottville to Springville as it does today; however, it initially overlapped NY 242 between Ellicottville and Ashford and utilized what is now NY 240 between Ashford and Cattaraugus Street southeast of Springville. Within Springville, US 219 was routed along Cattaraugus Street and Buffalo Street and intersected NY 39 in the village center. Outside of the village, US 219 went north on Springville–Boston Road and Boston State Road to North Boston, from where US 219 continued to Hamburg by way of modern NY 391.[23]

In the early 1950s, construction began on a western bypass of Springville that connected US 219 just north of the village to East Otto Road 6 miles (10 km) south of Springville. The portion of the highway north of Waverly Street was completed by 1954.[24][25] The remainder of the bypass was finished by 1956, at which time US 219 was realigned to follow the bypass around the village. At the south end of the bypass, US 219 continued south to Ellicottville by way of pre-existing, previously unnumbered highways.[26] However, the segment of modern NY 240 vacated by US 219 did not become part of an extended NY 240 until the mid-1960s.[27][28] In the 1990s, US 219 was rerouted to follow the Southern Tier Expressway between exit 21 in Salamanca and exit 23 just south of Bradford Junction. The old alignment of US 219 through Carrollton and Salamanca became US 219 Business.[29][30]

Construction began in the early 1970s on the Southern Expressway, a limited-access highway connecting Buffalo to Springville. The first segment of the expressway—between the New York State Thruway east of Lackawanna and US 20A west of Orchard Park—opened to traffic by 1973 as a realignment of US 219. In between the end of the expressway and North Boston, US 219 temporarily overlapped US 20A and NY 277.[31][32] The freeway was extended south to North Boston in the mid-1970s[33][34] and to Springville in the early 1980s. Both segments became part of US 219 upon opening.[35][36] The former surface routing of US 219 between North Boston and Hamburg was redesignated as NY 391 following the completion of the expressway's first segment in the early 1970s[31][37] while the remainder of US 219's former routing south to Springville was transferred to Erie County upon the completion of the entire Springville–Buffalo segment of the Southern Expressway.[38]

Plans to extend the Southern Expressway southward from NY 39 in Springville to Peters Road in Ashford, a distance of 4.2 miles (6.8 km), had been in development for years before they were finally put into action in the mid-2000s.[10] Project specifications called for the installation of a four-lane right-of-way (two lanes in each direction) and the construction of 11 bridges, including twin bridges over Cattaraugus Creek.[39] The number was later revised to nine.[10] Areas near parts of the new freeway were to become a 41-acre (17 ha) wetland habitat.[10][39] A portion of NY 39 near the current southern terminus was also reconstructed in 2007 and 2008 to accommodate for the completed interchange with US 219.[39]

The rights to the project were awarded to Cold Spring Construction on January 26, 2007, with work commencing on June 1.[39] Altogether, the project was initially expected to cost $86 million[40] and be completed in late 2009. The lengthy construction time was largely due to the need to construct two bridges over the Zoar Valley gorge.[41] As of March 2009, the projected cost of the extension had risen to $116 million. Since 2007, the project had encountered several delays due to landslides in the vicinity of Scoby Hill Road and the need to conduct a second environmental impact study on the road's impact on wetlands in the area. As a result, the $86 million in state funding that was devoted to the project was reallocated to other projects in New York, a move confirmed by the New York State Department of Transportation (NYSDOT) in March 2009. At the same time, however, NYSDOT left open the possibility of eventually restoring the funding.[40][42] It was restored sometime afterward, and the highway was completed on November 19, 2010,[43] with a total price tag of $125 million.[44]

Ownership and maintenance of the former surface alignment of US 219 north of Peters Road—now known as Miller Road, and including the two-lane, high-level bridge that currently carries it across the valley surrounding Cattaraugus Creek—was transferred from the state of New York to Erie and Cattaraugus counties. The two sections of road leading to and from the bridge were transferred immediately while the bridge itself was not turned over until a state-funded rehabilitation project was completed in 2013. The latter half of the plan drew criticism from Erie County officials who believe that the state should continue to maintain the bridge due to its size, importance and the resulting cost of upkeep.[45] Because of safety concerns, the bridge was closed to traffic on January 5, 2012 and remained closed until April of that year while repairs were made to the structure.[46] The section of US 219 between the Cattaraugus County line and Waverly Street in Springville became County Route 581.[47] The section in Cattaraugus County became County Route 100.[48]

On July 6, 2014, the New York State Department of Transportation announced the extension of the Western New York Southtowns Scenic Byway, a scenic byway through Erie County from Orchard Park to Springville,[49] into Cattaraugus County. The new extension would involve US 219 from NY 39 in Springville to the Great Valley town line and NY 240 down to NY 39 and NY 242.[50]
