New York State Route 19A (NY 19A) is a north–southstate highway inwestern New York in the United States. It is an alternate route ofNY 19 between the town ofHume (at thehamlet ofFillmore) and the vicinity of the village ofSilver Springs. NY 19A also serves the community ofPortageville and thevillage of Castile. The portion of NY 19A south of Portageville closely follows theGenesee River. North of Portageville, the route parallels theSouthern Tier Line. NY 19A was assigned as part of the1930 renumbering of state highways in New York.
NY 19A begins at an intersection withNY 19 in thehamlet ofFillmore, a former village in the town ofHume. It initially heads north through the northern portion of the community. Outside of Fillmore, the route curves to the northeast and heads through open, cultivated fields as it parallels theGenesee River, located to the southeast of NY 19A. Near theAllegany–Wyoming county line, NY 19A turns to follow a more northerly routing, matching a similar turn in the course of the nearby river.[3]

Now in the Wyoming County town ofGenesee Falls, the landscape surrounding NY 19A becomes more forested as the highway approachesLetchworth State Park. NY 19A continues along the western bank of the Genesee River to the hamlet ofPortageville, a riverside community located at the southern tip of the park. Here, NY 19A intersectsNY 436 in the center of the community. NY 436 joins NY 19A here, and the two routes leave Portageville to the northwest. For the most part, NY 19A and NY 436 pass southwest of Letchworth State Park; however, they do connect to the park by way of a local park road just north of Portageville. In this area, the Genesee River turns northeast to flow through the park instead.[3]
Theoverlap between NY 19A and NY 436 comes to an end 2 miles (3.2 km) northwest of Portageville at a junction known as Bigelow Corners. NY 436 heads west into thetown of Pike; however, NY 19A continues northward along theSouthern Tier Line, a railroad line owned by theNorfolk Southern Railway, into thetown of Castile. Here, the forests that had surrounded NY 19A begin to give way to open fields as the route heads away from Letchworth State Park. NY 19A meetsNY 39 just southwest of thevillage of Castile, and the two routes overlap for a mere 0.2 miles (0.3 km) into the village limits. After crossing the village line, NY 19A leaves NY 39 and heads northwest into thetown of Gainesville. The route turns back to the north just west of the town line and continues onward through fields and forests toward the village ofSilver Springs.[3]
Silver Springs is the largest location along NY 19A; however, NY 19A is the only state highway that directly serves the village. It heads north through the residential western half of the village as Cummings Avenue to Perry Avenue, where it makes a turn to the west to avoid the junction of the Southern Tier Line and theRochester and Southern Railroad. The route becomes Warsaw Boulevard upon rounding the curve; however, this name is dropped upon exiting the village. NY 19A continues through Gainesville and passes by cultivated fields and forested areas to a junction with NY 19, where it terminates.[3]
In 1908, theNew York State Legislature created Route 16, an unsignedlegislative route that initially extended fromCuba toRochester viaFillmore,Warsaw, andLe Roy. At the time, Route 16 utilized modernNY 19 between Fillmore and Rock Glen, ahamlet south of Warsaw.[4][5] On March 1, 1921, the route was realigned between the two locations to use current NY 19A instead.[6] However, whenNY 62 was assigned to most of legislative Route 16 betweenBelfast andPavilion in the mid-1920s, it utilized the pre-1921 routing of Route 16 viaPike.[7][8] The post-1921 alignment of legislative Route 16 between Fillmore and Rock Glen viaSilver Springs remained unnumbered until the1930 renumbering of state highways in New York when it became NY 19A,[2] an alternate route of the newly assigned NY 19, itself renumbered from NY 62.[9]
