Montauk Highway (NY-27A / CR-80 / NY-27)

Montauk Highway is one of Long Island’s most historic and recognizable roadways, following the South Shore corridor east toward Montauk Point. On modern maps, the name applies to a mix of signed and locally maintained segments – including stretches associated with NY-27A, Suffolk County’s CR-80, and NY-27 farther east – rather than one uninterrupted designation for the entire trip.
In practice, travelers use Montauk Highway to reach downtown villages, marinas, beaches, and the Hamptons. Drivers approaching from Queens typically connect into the broader South Shore route through Nassau County before the Montauk Highway name becomes more prominent farther east. It is generally slower and more local than Sunrise Highway, but that is also part of its appeal: the road passes through traditional business districts, waterfront communities, and scenic East End stretches that the expressway largely bypasses.
