Montauk Highway begins at the Nassau–Suffolk county line, where it connects to Merrick Road. It heads east along the southern shore of Long Island, carrying NY 27A from Amityville to Oakdale. The highway generally narrows to two lanes in most places, especially through communities of which it forms the main street, such as Amityville, the village of Babylon, Bay Shore, the hamlet of Islip, Oakdale, Sayville and Patchogue. In these places, Montauk Highway is often called Main Street. In addition to being called Montauk Highway and Main Street in Suffolk County, it is also historically known as South Country Road, a name that is only used by former segments today.

NY 27A ends at NY 27 exit 46A in Oakdale, giving way to CR 85 along Montauk Highway. As CR 85, Montauk Highway runs through the hamlets of Oakdale, West Sayville, Sayville, Bayport, and Blue Point to the village of Patchogue, where the designation ends at CR 19. East of CR 19, Montauk Highway (known within the village as West and East Main streets) continues as a village-maintained street to the eastern village line, where it becomes CR 80, the designation that comprises most of Montauk Highway. Proceeding east from Patchogue, Montauk Highway runs through progressively less-densely populated communities. The segment east of Station Road in North Bellport and CR 36 in Brookhaven still contains old concrete pavement, a common practice of the mid-20th century. East of Speonk, the highway enters the Hamptons, the small-town, farming and summer resort communities especially popular with New York City summer vacationers.

Montauk Highway forms the main street of most of the communities in the Hamptons, such as Westhampton, Quogue, and Hampton Bays. CR 80 ends west of the village of Southampton at Knoll Road, at which point Montauk Highway becomes state-maintained again as NY 900W, an unsigned reference route. This ends at the Southampton village line, leaving Montauk Highway as a village-maintained street until it reconnects to NY 27 northeast of the village center. Now part of NY 27, Montauk Highway is the major, and occasionally the only through road in the area, passing through Bridgehampton, East Hampton, and Amagansett to reach Montauk. The highway and NY 27 end at a loop in the road at Montauk Point.
