It runs from an intersection with East Main Street (former NY&nbsp;27A) in the village of Patchogue to a junction with NY&nbsp;25A in Port Jefferson Station. It is known locally as Medford Avenue in Patchogue and Patchogue Road in Terryville and Port Jefferson Station. The official name for the road outside these areas is "Patchogue–Port Jefferson Road", though it is often signed simply as "Route&nbsp;112".<ref>[https://maps.google.com/maps/svpw?url=https:%2F%2Fmaps.google.com%2Fmaps%3Ft%3Dh%26q%3D40.817778,-72.986111%26ie%3DUTF8%26ll%3D40.817778,-72.986111%26spn%3D0.01978,0.027595%26z%3D14%26vpsrc%3D6%26layer%3Dc%26cbll%3D40.815585,-73.00023%26panoid%3DqhQ5XUkB6WqD3w12XtIYcg%26cbp%3D12,272.38,,2,0%26output%3Dembed&hl=en&gl=us Street name sign at NY 112 and Peconic Avenue, Medford, New York (Google Street View)]</ref>

== Route description == NY&nbsp;112 begins at an intersection with 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&nbsp;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&nbsp;53 of Sunrise Highway (NY&nbsp;27) in the census-designated place of North Patchogue. NY&nbsp;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&nbsp;99 (Woodside Avenue), a four-lane arterial through Brookhaven.<ref name="bing">{{bing maps|url=http://binged.it/IKGs6U|title=overview map of NY 112|accessdate=May 2, 2012}}</ref>

Continuing north from CR&nbsp;99, NY&nbsp;112 condenses down to two lanes (one in each direction), remaining a commercial arterial. NY&nbsp;112 passes Tremont Elementary School before crossing Greenport Road, continuing northward into the census-designated place of Medford. In Medford, NY&nbsp;112 continues north, crossing under the Long Island Rail Road's Greenport Branch next to the Medford station. After crossing under the tracks, NY&nbsp;112 continues northeast through Medford, entering interchange&nbsp;64 of the Long Island Expressway (I-495) and expanding to four lanes once again before an intersection with CR&nbsp;16 (Horse Block Road). The route returns to two lanes after CR&nbsp;16, passing east of Blue Ridge Golf Club and Holy Sepulchre Cemetery. At this point, NY&nbsp;112 changes names from Medford Avenue to Port Jefferson–Patchogue Road.<ref name="bing" /> left|thumb|NY&nbsp;112 approaching its northern terminus, an intersection with NY&nbsp;25A in Port Jefferson Station Continuing north through Brookhaven, NY&nbsp;112 intersects a former alignment of itself, entering the census-designated place of Coram. In Coram, NY&nbsp;112 bends to the northwest at an intersection with Grand Smith Road, immediately intersecting with NY&nbsp;25 (Middle Country Road). The two roads parallel each other westward, NY&nbsp;112 becoming a residential street in the middle of a large housing complex in Coram before turning northward and into an at-grade interchange with CR&nbsp;83 (Patchogue–Mount Sinai Road). NY&nbsp;112 continues north out of the interchange and Coram, turning northwest as a two-lane residential arterial. After Birchwood Road, NY&nbsp;112 becomes commercial once again, bending further to the northwest.<ref name="bing" />

After the bend, NY&nbsp;112 continues through Brookhaven, crossing a large shopping plaza into the census-designated place of Port Jefferson Station. In Port Jefferson Station, NY&nbsp;112 intersects with NY&nbsp;347 (Nesconset Highway), a wide arterial boulevard in the town of Brookhaven. The route continues northwest away from NY&nbsp;347 as a four-lane commercial street, now under the moniker of Patchogue Road. Just after entering the downtown portion of Port Jefferson Station, NY&nbsp;112 intersects with NY&nbsp;25A (Hallock Avenue). At this intersection, NY&nbsp;112 terminates, the right-of-way continues north as NY&nbsp;25A and Main Street, connecting to the namesake train station on the Port Jefferson Branch.<ref name="bing" />

When the Long Island Expressway (Interstate&nbsp;495) was built across central Suffolk County between 1969 and 1971, NY&nbsp;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.<ref>{{cite news |newspaper=Newsday |location=New York City |date=February 28, 1999 |title=Ask Dr. Conehead}}</ref><ref name="ReferenceA">{{cite news |newspaper=Newsday |location=New York City |date=February 27, 2000 |title=Ask Dr. Conehead}}</ref>
