New York State Route 112

State highway in Suffolk County, New York, US

NY 112 begins at an intersection with County Route 80 (CR 80; East Main Street) in the village of Patchogue. The route proceeds northward as a four lane commercial street as Medford Avenue. Near the intersection with Lakewood Street, NY 112 leaves the village of Patchogue, entering the town of Brookhaven. The route does not change going north, passing Medford Elementary School before entering interchange 53 of the Sunrise Highway (NY 27) in the census designated place of North Patchogue. NY 112 crosses over the Sunrise, continuing north as Medford Avenue as the four lane boulevard it was prior to the interchange. At the intersection with Shaber Road, the route bends to the northeast, changing names to Medford Road and crossing an intersection with CR 99 (Woodside Avenue), a four lane arterial through Brookhaven. Continuing north from CR 99, NY 112 condenses down to two lanes (one in each direction), remaining a commercial arterial. NY 112 passes Tremont Elementary School before crossing Greenport Road, continuing northward into the census designated place of Medford. In Medford, NY 112 continues north, crossing under the Long Island Rail Road's Greenport Branch next to the Medford station. After crossing under the tracks, NY 112 continues northeast through Medford, entering interchange 64 of the Long Island Expressway (I 495) and expanding to four lanes once again before an intersection with CR 16 (Horse Block Road). The route returns to two lanes after CR 16, passing east of Blue Ridge Golf Club and Holy Sepulchre Cemetery. At this point, NY 112 changes names from Medford Avenue to Port Jefferson–Patchogue Road. serving as the main thoroughfare for New England residents taking stagecoaches from Port Jefferson to Patchogue. Additionally, the Medford Avenue segment in Patchogue and North Patchogue was part of the historic Long Island Bicycle Path, which ran from Patchogue to Port Jefferson in the 1890s and into the early 20th century. Most of the old stage road was acquired by the state of New York in 1913; however, the section within the Patchogue village limits did not become state maintained until the 1920s. The Patchogue–Port Jefferson state highway did not receive a posted designation until the 1930 renumbering of state highways in New York, when it became NY 112. Parts of NY 112 have been realigned to bypass curves or turns in the original stage road. One former segment lies behind a New York State Department of Transportation (NYSDOT) maintenance yard in Coram. Other highways that were once part of NY 112 include part of Middle Island Road and an abandoned road in Medford; a section near Pine Road in Coram; and a segment near East Gate in Terryville. In the 1960s and 1970s, NYSDOT wanted to realign both NY 112 and NY 25 in Coram. Plans to realign NY 112 in this area date as far back as the 1930s. The route originally crossed the Long Island Rail Road in Medford by way of a dangerous grade crossing. 13 years after a driver was killed while traversing the crossing. In 1964, the segment of NY 112 in Patchogue between East Main and Clark streets was widened to four lanes. When the Long Island Expressway (Interstate 495) was built across central Suffolk County between 1969 and 1971, NY 112 was widened to a four lane divided highway in the vicinity of the new expressway. This project included tilting the curved embankment of the southbound lane, which has created a series of floods in moderate to heavy rainstorms.
