New York State Route 252

State highway in Monroe County, New York, US

As Ballantyne Road, the route progresses northeastward, paralleling Black Creek as it crosses the Rochester and Southern Railroad. Roughly 0.5 mile (1 km) past the railroad crossing, the road curves to the southeast, entering a residential area as it approaches the Genesee River and NY 383 (Scottsville Road), which runs along the river's western bank. At NY 383, NY 252 becomes Jefferson Road, a name that follows NY 252 eastward to its terminus in the village of Pittsford. NY 252 traverses the river and enters the town of Henrietta by way of the Ballantyne Bridge. On the opposite bank of the river, NY 252 intersects East River Road, Scottsville Road's counterpart on the eastern river bank. It was extended northwest to NY 33A and then NY 251 (now NY 386) in the hamlet of Chili Center via Scottsville and Paul roads on January 1, 1949, replacing NY 198. In November 1955, NY 96 was realigned onto the new Eastern Expressway from Bushnell's Basin to East Rochester. Its former surface routing between the village of Pittsford and Bushnell's Basin became part of an extended NY 252. The west end of NY 252 was altered in the late 1950s to follow Ballantyne, Archer, and Beaver Roads between NY 33A and NY 383, while the east end was truncated back to Pittsford c. no – c. 1961 when the Eastern Expressway was redesignated as I 490. The former routing of NY 252 along Paul Road was redesignated as NY 252A. The portion of NY 252 west of NY 383 was originally maintained by Monroe County. This section was concurrent with three different county route designations, one for each of the three different road names along this stretch. The portion of NY 252 on Ballantyne Road was designated by Monroe County as County Route 125 (CR 125) while the Beaver Road segment was CR 127 and the Archer Road piece was CR 129. In 2007, ownership and maintenance of NY 252 west of NY 383 was transferred from Monroe County to the state of New York as part of a highway maintenance swap between the two levels of government. A bill (S4856, 2007) to enact the swap was introduced in the New York State Senate on April 23 and passed by both the Senate and the New York State Assembly on June 20. The act was signed into law by Governor Eliot Spitzer on August 28. Under the terms of the act, it took effect 90 days after it was signed into law; thus, the maintenance swap officially took place on November 26, 2007. The entirety of NY 252 is now maintained by the New York State Department of Transportation (NYSDOT).

The 1902 Plat Map of Monroe County NY, Plate 21, shows a road in the northeast corner of the Town of Henrietta, called Croton Road, running west from the Pittsford Town border, terminating after about a mine and a quarter at a road now known as Winton Road South. This portion of Croton Road follows the modern alignment of Jefferson Road, Rt. 252. A traveler from Pittsford Village to the Ballentyne bridge over the Genesee River would follow this road to Winton Road, turn north on Winton to the beginning of Brighton Henrietta Town Line Road, and then follow that road west to the bridge. The 1924 Monroe County Plat Map shows the same road layout, except that Croton Road is called Lothrudge in the Town of Henrietta. But the 1941 Monroe County Plat Map, Vol. 5, Plat 26 and 27, shows the bypass alignment of Jefferson Road, State Highway Route 252, where the former Crodon (or Lothrudge) Road continues directly west of Winton Road South, intersecting East Henrietta Road (State Highway Route 15A), Clay Road, West Henrietta Road (US and State Highway Route 15), where it angles to the northwest and intersects Brighton Henrietta Town Line Road at Johns Street in the hamlet of Mortimer. The portion of Brighton Henrietta Town Line Road west of Johns Street, as seen on the 1902 and 1924 Plat Maps, has been renamed Jefferson Road on the 1941 Plat Map. Mortimer is marked as the intersection of the New York Central Rail Road, West Shore Division, running east and west (between Jefferson Road and Brighton Henrietta Town Line Road), The Rochester and Mount Morris branch of the Erie Railroad, running to the southwest, and the Rochester spur of the Lehigh Valley Railroad, running to the southeast.

In August 2008, construction began on a $5.5 million project to improve the intersection between Clover Street (NY 65) and Jefferson Road (NY 252) in the town of Pittsford. The project, which had been in development for a decade, involved the widening of Jefferson Road from two to four lanes in the vicinity of the intersection, the addition of green arrow signal lights for all left hand turns, and the installation of sidewalks alongside both Clover Street and Jefferson Road. Work on the project was temporarily halted during the winter months; however, it resumed on April 1, 2009. The project was completed in late 2009. The portion of NY 252 in Henrietta between Marketplace Drive and Ridgeland Road was widened from four to six lanes as part of a multi year, $15.6 million project that began in mid 2009. Phase one of the five phase project, completed during the second half of 2009, involved the relocation of utility poles and water mains. The next four phases involved the actual widening of the highway. During phase two, all traffic on Jefferson Road was routed along the eastbound lanes while the westbound half of the road was reconstructed and widened; this was reversed during phase three. A raised median between the two directions, which prohibited left hand turns at all points except signalized intersections, was constructed during phase four, and phase five covered the finishing touches of the project. As part of the project, the intersection between Jefferson Road and East Henrietta Road (NY 15A) was widened to have two dedicated left turn lanes in all four directions. Work on the last four phases began on March 29, 2010, and was expected to be fully completed in November 2011.

NY 252A (4.40 mile (7 km)) was an alternate route of NY 252 along Paul Road in the town of Chili. It extended from the eastern terminus of the overlap between NY 33A and NY 386 in the hamlet of Chili Center to NY 383 in the vicinity of the Greater Rochester International Airport. Despite its designation, NY 252A never connected to NY 252. Its former alignment is now maintained by Monroe County as part of CR 168.
