context_page_description: New York State Route 27 is a 120.58-mile long state highway that runs east-west from Interstate 278 in the New York City borough of Brooklyn to Montauk Point State Park on Long Island, New York. Its two most prominent components are Sunrise Highway and Montauk Highway, the latter of which includes the Montauk Point State Parkway. NY 27 acts as the primary east-west highway on southern Long Island east of the interchange with the Heckscher State Parkway in Islip Terrace. The entire route in Suffolk, Nassau, and Queens counties were designated by the New York State Senate as the POW/MIA Memorial Highway. The highway gives access to every town on the South Shore. NY 27 is the easternmost state route in the state of New York.
  NY 27 has service roads that parallel the highway continuously from North Lindenhurst to Patchogue, and intermittently to the east into Southampton. They are officially designated, but not signed, as New York State Route 906C and New York State Route 906D.
context_section_description: Robert Moses developed plans for an elevated expressway featuring 10 to 12 lanes along Sunrise Highway through Nassau County. This expressway would have provided a truck link for the South Shore of Long Island but the downtown villages along the route effectively put a stop to the idea. 
  The portion of Sunrise Highway between North Lindenhurst and the town of Southampton was gradually upgraded to a limited-access highway. At the east end of NY 27 the highway abruptly became a three-lane highway east of the Shinnecock Canal, at the point where NY 27 is concurrent with CR 39. This area was known as the "Shinnecock Squeeze" as traffic on the two-lane eastbound NY 27 was "squeezed" into a single lane.
  In 2006 and 2007 Suffolk County and Southampton officials began using traffic cones to adjust the lanes to accommodate peak travel in what was called the "traffic cone program".
  At the end of summer 2007, another eastbound lane was added, heading eastward to North Sea Road. The construction snarled traffic on CR 39. The Long Island Rail Road added three trains each way between Speonk and East Hampton during the construction. In April 2008, the three-lane segment from North Sea Road to Flying Point Road was reconfigured from one eastbound and two westbound lanes to two eastbound and one westbound lane. The merge from two lanes to one in the eastbound direction is now assisted by a signalized intersection at Flying Point Road, where eastbound NY 27 traffic makes a left turn onto Montauk Highway. This widening project eliminates the "Shinnecock Squeeze."
