The Sunken Meadow State Parkway (also known as the Sunken Meadow) is a long parkway in Suffolk County, Long Island, New York. Located entirely within the town of Smithtown, the parkway begins at a cloverleaf interchange with the Northern State Parkway (exits 44–45) and the northern terminus of the Sagtikos State Parkway. The parkway, which continues north, is a northern spur of the Sagtikos, which opened in September 1952. The northern end of the parkway is at the toll barrier in exit SM5 in the Kings Park section of Smithtown. From there, the road continues north through Sunken Meadow State Park to a roundabout at the Long Island Sound. The parkway comprises the northern half of New York State Route 908K (NY 908K, an unsigned reference route), with the Sagtikos State Parkway forming the southern portion. Commercial vehicles are, like on most parkways, prohibited from using the Sunken Meadow, except for a portion north of NY 25A in Kings Park. The parkway was first proposed in 1928 when the town of Smithtown deeded over of land to the Long Island State Park Commission via public vote. Due to land use restrictions in Nassau County, Sunken Meadow was the first park east of New York City, because provisions for a parkway would be near impossible to build. Construction of the parkway commenced after the Sagtikos opened in September 1952, with the interchange at the Northern State Parkway. The first portion opened to traffic in November 1954 from the Northern State/Sagtikos to NY 25, with a slated completion in 1956. The parkway was completed in April 1957, opening on the 1st. As part of the parkway opening, improvements were made to Sunken Meadow State Park, including expanded vehicle capacity and a longer boardwalk. In 2001, the Sunken Meadow was proposed in a study to receive a widening, which would include new bus and carpool lanes. ==Route description== The Sunken Meadow State Parkway begins at exit 44–45 off the Northern State Parkway, a cloverleaf interchange that also serves as the northern terminus of the Sagtikos State Parkway. Southbound, this interchange is designed as exit SM1. After the Northern State, the Sunken Meadow continues northeast on the right-of-way used by the Sagtikos, crossing through Commack. Passing west of Valmont Village Park, the four-lane parkway crosses under New Highway, bending northeast through Commack, becoming a divided parkway as it enters exit SM2. This exit, which is only served northbound, connects the Sunken Meadow to NY 454 (Veterans Memorial Highway) via Harned Road, a local street in Smithtown. The four-lane parkway continues northward through Candy Section, crossing under NY 454 a short distance after the interchange. At the overpass, the westbound entrance from NY 454 connects to the southbound Sunken Meadow. Immediately after crossing under NY 454, the Sunken Meadow State Parkway continues northward into exit SM3, which serves as a cloverleaf interchange with NY 25 (Jericho Turnpike). The four-lane parkway continues north out of the interchange, immediately entering exit SM3A, which northbound connects to County Route 14 (CR 14; Indian Head Road). Southbound, this interchange serves Old Indian Head Road, and is signed as part of exit SM2. After exit SM3A, the Sunken Meadow bends northeast, becoming a divided highway once again, crossing through Smithtown. The parkway bends north once again, crossing under Scholar Lane before paralleling Old Commack Road under Old Northport Road. After a bend to the northeast, the parkway enters Kings Park.〔 In Kings Park, the Sunken Meadow State Parkway bends northward, crossing under the Long Island Rail Road's Port Jefferson Branch and entering exit SM4. Exit SM4 is a cloverleaf interchange that serves CR 11 (Pulaski Road / East Northport Road). After the interchange with CR 11, the Sunken Meadow enters Fort Salonga as a four-lane parkway with a wide median, bending northeast into exit SM5. Exit SM5, the last on the Sunken Meadow, is a cloverleaf interchange with NY 25A (Fort Salonga Road). After crossing over NY 25A, the Sunken Meadow State Parkway enters Sunken Meadow State Park at a toll barrier in the middle of the interchange. The toll barrier serves as the northern terminus of the Sunken Meadow State Parkway, while the right-of-way continues north through Sunken Meadow State Park, terminating at a roundabout near the Long Island Sound.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sunken Meadow State Parkway」の詳細全文を読む スポンサード リンク
