ROUTE DESCRIPTION

NY 27A starts out at the intersection of Sunrise Highway , Old Sunrise Highway and Carman Mill Road in eastern Massapequa. Once at the intersection, NY 27A travels south (east on the route shield) along Carman Mill Road for 6/10 of a mile to Merrick Road. Once at Merrick Road, NY 27A makes a left, heading eastbound as an unsigned route to the Nassau/Suffolk County border. Once in Suffolk County, NY 27A is a full-fledged state route with Reassurance Shield s and Reference Marker s. NY 27A remains Merrick Road through Amityville until it reaches Copiague , where it becomes Montauk Highway to its terminus in Oakdale. Along the route, Montauk Highway is also called South Country Road and Main Street. East of Heckscher State Parkway , NY 27A is lined with parkway style lampposts. At its terminus at NY 27 in Oakdale, NY 27A becomes County Route 85 , then Main Street in Patchogue , and County Route 80 east of Patchogue.

HISTORY


Bay Shore Split


Realizing that traffic would increase along NY 27A, the Suffolk County Planning Department proposed a major reconstruction project of Downtown Bay Shore in cooperation with the New York State Department Of Transportation that would reroute eastbound and westbound traffic around the current NY 27A, and transform it into a pedestrian mall, with parking garages at key locations. This plan was scrapped by public opposition, as many proposed highway projects were during the late-20th Century.

MISCELLANEA


Parkway Truck Access

Geographically, NY 27A is the southernmost state route that, under normal state laws, can be employed by Truck s. However, some parts of Long Island's barrier beaches are south of this road and can ''only'' be reached by accessing the parkways, which trucks cannot normally use. Because of this, a conditional exemption is in place. A truck making a delivery to the beaches may employ the parkways, but only if they enter and exit no farther north than this road or its Nassau counterpart, former Nassau County Route 27A.


Truck 27A



  • In 1960, Suffolk County transformed Frowein Road between Moriches and East Moriches into the Moriches Bypass. This was designated as New York State Truck Route 27A, but it was also '''Suffolk County Route 98'''. When the NY 27A designation was deleted east of Great River , the County Road 98 designation became more prominent.


  • Also in the early 1970s, a reconstruction project of NY 27A took place between Hampton Bays and Shinnecock Hills , creating a route known as Temporary Truck NY 27A, which ran between NY 24 , then along NY 27 between exits 65 and 66, and then to North Road south of NY 27.
