Major east–west state highway in New York, US
The areas NY 3 passes through alternate between long stretches of rural area, consisting of a mix of open terrain and dispersed residences, and compact settlements containing concentrations of houses and businesses. NY 3 is classified mainly as a minor arterial road, the major exception being the section that is concurrent with NY 812, which is a principal arterial road. Most of the route is maintained by the New York State Department of Transportation. Exceptions are in the cities of Watertown and Plattsburgh, where at least part of the road is city maintained. In Watertown, NY 3 is locally maintained from Massey Street (southbound US 11 junction) to the end of the NY 3/NY 12 overlap. The route is entirely city maintained in Plattsburgh.

NY 3 begins at an intersection with NY 104A in Sterling. NY 3 continues east to meet NY 104 in the center of Hannibal. From there, NY 3 progresses across Oswego County and passes Lake Neatahwanta prior to entering Fulton. Within Fulton, NY 3 intersects NY 48 on the west bank of the Oswego River before crossing the river and meeting NY 481 at the eastern bank. East of the city, NY 3 passes south of the Oswego County Airport as it heads to the northeast through Palermo. Upon intersecting NY 264, NY 3 becomes signed as a north–south highway instead of as an east–west route. It proceeds north to the village of Mexico, where it meets NY 104 once again. NY 3 and NY 104 overlap briefly through the western portion of the village before separating at the center of Mexico. While NY 104 heads east toward Williamstown, NY 3 heads north toward the hamlet of Texas. East of Texas, NY 3 meets NY 104B near the Lake Ontario shoreline. Past NY 104B, NY 3 parallels both Interstate 81 (I 81) and US 11 as it heads along the shore of Lake Ontario. Near the Selkirk Shores State Park west of Pulaski, NY 3 intersects NY 13 adjacent to the mouth of the Salmon River. After crossing the Salmon River, NY 3 passes the Sandy Island Beach State Park before entering Jefferson County. At the county line, NY 3 becomes signed as an east–west highway once again. The route continues northward toward Ellisburg where it meets NY 193 at the entrance to Southwick Beach State Park northwest of the community. Past NY 193, NY 3 passes the lakeside at Westcott Beach State Park prior to entering the vicinity of Sackets Harbor. The route bypasses both Sackets Harbor and the Sackets Harbor Battlefield State Historic Site to the east before separating from Lake Ontario and proceeding eastward toward Watertown.

In Black River, northeast of Watertown, NY 3 intersects NY 342 at the southwestern tip of the Fort Drum Military Reservation. NY 3 follows the southern edge of the base to Deferiet, where NY 3 turns south to follow the Black River while NY 3A continues along the border of Fort Drum. NY 3 follows the river to Carthage, where it overlaps NY 126 briefly before heading northeast to rejoin NY 3A at Fargo. NY 3 forms the southern boundary of the base from NY 3A east to just west of the Jefferson Lewis County line; however, near Natural Bridge, the Fort Drum boundary heads due north before becoming delimited by the Indian River. NY 3, meanwhile, traverses the river and enters Lewis County.

NY 3 originally followed a vastly different alignment than it does today. In 1924, it was assigned to the New York portion of the Theodore Roosevelt International Highway, an auto trail that extended from Portland, Maine, to Portland, Oregon. In New York, it connected North Tonawanda (near Niagara Falls) in the west to Plattsburgh in the east via Rochester and Watertown. NY 3 began at what is now the intersection of US 62 and NY 425 and followed modern NY 425 north through Cambria Station to Cambria Center, from where the highway continued to Lockport on Lower Mountain, Gothic Hill, and Upper Mountain Roads and modern NY 31. It remained on current NY 31 through the city and mostly followed that route's modern alignment across western New York to the city of Rochester. The most significant exception to this was between Lockport and Gasport, where NY 3 veered south by way of modern NY 77 and County Route 10 (CR 10) to serve the hamlet of McNalls. Within Rochester, NY 3 remained on the current alignment of NY 31 to what is now the intersection of Lyell Avenue and Broad Street. Here, NY 3 broke from modern NY 31 and continued east on Lyell Avenue to State Street. NY 3 then followed State Street, Main Street, and East Avenue (modern NY 96) through downtown before turning north onto Culver Road in the eastern portion of the city. The route remained on Culver Road to Empire Boulevard, where it turned east toward Irondequoit. Once in Irondequoit, it followed what is now NY 404 around the southern extent of Irondequoit Bay to Webster. NY 3 was realigned by 1930 to stay on East Avenue to Winton Road near the eastern edge of the city. Here, the route turned north, following Winton Road through eastern Rochester to Irondequoit, where it rejoined its previous routing at Empire Boulevard. Past Webster, NY 3 followed Ridge Road through Wayne County to Red Creek, where it continued northeast on what is now NY 370 and NY 104A through Red Creek, Fair Haven, and Sterling to western Oswego County. At Southwest Oswego, NY 3 joined the routing of modern NY 104 through Oswego and Mexico to Maple View. East of Clayton, it followed modern NY 12, NY 26 and CR 192 through Alexandria Bay to Redwood. From there, it utilized the current alignment of NY 37 up through Ogdensburg (by way of Main and Ford Streets in the city) before continuing to Waddington on Van Rensselaer Road. NY 3 went east from here along a now dismantled riverside highway and Town Line Road to Massena, where it was routed on modern NY 37B. NY 3 was realigned in two locations between Lockport and Rochester. One was just east of Lockport, where it was straightened out to go directly from Lockport to Gasport on modern NY 31, bypassing McNalls. The other was between Middleport and Medina, where it was realigned to use modern NY 31E instead. NY 3's old alignment from Lockport to Gasport via McNalls became part of NY 77 west of McNalls and NY 359 north of the community. The most significant realignment that occurred at this time was in the North Country, where NY 3 was shifted onto its current alignment between Watertown and Plattsburgh. From Tupper Lake east to Plattsburgh, most of what became NY 3 was previously part of NY 10. The NY 10 designation remained in place from Tupper Lake east to Upper Saranac Lake, forming an overlap with NY 3; however, it was completely replaced by NY 3 from Saranac Lake east. Between Upper Saranac Lake and Saranac Lake, the routing of NY 3 was previously unnumbered, as was the routing from Watertown to Tupper Lake. NY 3 was shifted southward onto modern NY 31 between Shawnee and Lockport c. no – c. 1932. The realignment eliminated overlaps with NY 425 and NY 93, the latter of which had used NY 3's former routing east of Cambria–Wilson Road since it was assigned as part of the 1930 renumbering. Even though all of the former routing had a designation, it was also designated as NY 3A anyway. As a result, the designations of all of NY 3's spur routes were increased by one letter, meaning the existing NY 3A became NY 3B, NY 3C became New York State Route 3D, and so forth. US 104 was assigned c. no – c. 1935, extending from Niagara Falls to Maple View mostly by way of then NY 31 west of Rochester and NY 3 from Rochester to Maple View. As a result, NY 31 was shifted southward onto the alignment of NY 3 from Niagara Falls to Rochester while NY 3 was realigned south of Watertown to follow the routing of NY 3D to a new terminus in Sterling. Every spur route of NY 3 was eliminated at this time except for NY 3G. The alignments of NY 3 and NY 3G between Deferiet and Wilna were flipped c. no – c. 1938.

At some point between 1935 and 1938, NY 3 was truncated further to end at its junction with US 104 in Hannibal. It was moved another half mile (0.8 km) to the east in the early 1960s following the completion of the super two bypass carrying US 104 around the eastern edge of the village. NY 3 continued to end at the super two until the early 1980s. On April 1, 1980, ownership and maintenance of NY 3's former routing between the Cayuga County line and NY 104 was transferred from Oswego County to the state of New York. One year later, on April 1, 1981, the state assumed ownership and maintenance of the Cayuga County portion from that county. Both transactions were part of larger highway maintenance swaps between the state and the two counties. NY 3 was reextended westward to NY 104A following the second swap. From Sandy Creek to Henderson, NY 3C (later NY 3D) was routed on Weaver Road, CR 121, NY 193, CR 78, NY 178, and CR 123. An extension of the roadway north to Henderson was completed by the following year. To the southwest in Oswego County, NY 3 was originally routed on modern CR 3 between Hannibal and Fulton and on Hannibal and Oneida Streets through the city of Fulton. The modern arterial through the city was constructed c. no – c. 1962 while the Hannibal–Fulton highway was built in the mid 1960s.

NY 3 has had 14 suffixed routes over the years; however, all of them except for one only existed during the 1930s. The only active designation is NY 3A, which is currently assigned to an alternate route of NY 3 in Jefferson County.

At least four suffixed routes of NY 3 were created as part of the 1930 renumbering of state highways in New York. NY 3B was an alternate route of NY 3 between Middleport and Knowlesville.
