Sagtikos State Parkway

The Sagtikos State Parkway begins at an interchange with the Southern and Heckscher state parkways in the hamlet of West Islip, just north of the Robert Moses Causeway's junction with the Southern State Parkway. Heading southbound, this junction is signed as exit S4. The parkway proceeds northward through the Town of Islip as a four-lane divided highway, passing through residential parts of the adjacent hamlet of Brentwood to reach exit S3, a partial cloverleaf interchange with Pine Aire Drive. Just north of the junction, the highway passes over the Main Line of the Long Island Rail Road. Continuing northward through Islip, the Sagtikos Parkway leaves Brentwood ahead of exit S2, a connection to County Route 13 (CR 13, named Crooked Hill Road). The southbound exit serves CR 13 by way of access roads through the Pilgrim Psychiatric Center while the northbound direction uses part of G Road to reach CR 13 and Suffolk County Community College's Grant Campus. Past the exit, the Sagtikos State Parkway crosses under CR 13 and immediately reaches the Sagtikos Interchange at exit S1 – a large, modified cloverleaf interchange with the Long Island Expressway (Interstate 495). The junction brings the parkway into the Town of Smithtown, where it bends northwestward and parallels CR 67 (Vanderbilt Motor Parkway) for a half-mile (0.8 km) through the town's Commack section. CR 67 eventually turns westward to pass over the Sagtikos Parkway, at which point the parkway curves back to the north and enters exit SM1E, a cloverleaf interchange serving as the Northern State Parkway's exit 44. The Sagtikos State Parkway name ends here while the highway continues northward toward Long Island's North Shore as the Sunken Meadow State Parkway. According to annual average daily traffic counts compiled in 2011 by NYSDOT, the most-traveled stretch of the Sagtikos State Parkway was the portion between the Southern State Parkway and the Long Island Expressway. The part between the Southern State and Pine Aire Drive handled an average of 87,250 vehicles per day; slightly lower numbers were recorded along the segment between Pine Aire Drive and the Long Island Expressway, with roughly 85,300 vehicles using the section on a daily basis. The portion between the Long Island Expressway and the Northern State Parkway carries an average of 67,600 vehicles per day. All three segments saw a rise in traffic over the course of the previous decade, with the Pine Aire Drive–Long Island Expressway segment gaining 14,000 vehicles per day during that time. ==History==

Construction and opening The Sagtikos State Parkway was first proposed in the 1920s as a connector between the Northern and Southern state parkways. In order to construct the freeway, the heirs of the late David Gardiner, who owned the historic Sagtikos Manor in West Bay Shore, donated of land to the Long Island State Park Commission (LISPC). This donation was considered unusual by the commission as it would break up the family's estate, which had been constructed in 1692 and served George Washington in 1780. In addition to this donation, James Fisher, a nearby resident, gave the commission of land north of the Gardiner property and another north of the Fisher property to ensure that LISPC had the necessary right-of-way for the new parkway. The right-of-way on which the parkway was built had originally been part of a private road leading to Sagtikos Manor. The parkway was designed to have connections with the Sunken Meadow Spur (the future Sunken Meadow State Parkway) and the Captree State Parkway (now known as the Robert Moses Causeway) proposed by New York City urban planner Robert Moses. On November 13, 1949, a new interchange between the Southern State Parkway and Bay Shore Road was opened to traffic. This interchange would eventually serve as the Southern State Parkway's junction with the Sagtikos, Heckscher and Captree state parkways. Proposals conceived at this time called for grading on the new Sagtikos State Parkway to begin in early 1950. In March 1950, $3 million (1950 USD) was earmarked out of a $104.5 million budget for the start of construction on the parkway. The contract for paving of the Sagtikos Parkway was awarded by the New York State Department of Public Works on June 7, 1951, to Hudson Contracting Corporation of Kew Gardens, who entered a bid of $1,407,037 (1951 USD) for the project. The remainder of the parkway was paved as part of a contract valued around $418,000 (1951 USD) and let by the state on July 11. A stretch of the Northern State Parkway was also built as part of the project. On September 29, 1952, an extension of the Northern State Parkway, Southern State Parkway, and the entire length of the Sagtikos State Parkway were opened without celebration. Robert Moses commented that the completed parkway reflected LISPC's objective to construct well-designed recreational facilities. Roadway improvements From 1997–2001, engineers from NYSDOT worked on a $6.5 million (2001 USD) study aimed to improve Long Island's transportation system by 2020. The resulting plan included proposals to widen of roads, including the entirety of the Sagtikos State Parkway – from the Southern State Parkway to the Northern State Parkway. In 2002, the Wolkoffs, a family of real estate developers, bought land used by the Pilgrim Psychiatric Center for $20 million (2002 USD) with the intent of redeveloping the property as a new smart growth community named Heartland Town Square. The community, situated near the interchange between the Sagtikos Parkway and the Long Island Expressway (I-495), would have 9,000 housing units and various commercial & recreational buildings. As part of the redevelopment of the property, a study was done on the existing facilities and the surrounding area, which noted several deficiencies in the area's transportation system – including several related to the Sagtikos. The study determined that the deficiencies would be "exacerbated" if no changes were made. In response, the study suggested that a third lane be constructed along the Sagtikos from the Southern State Parkway to the Long Island Expressway. The bridges over the Sagtikos at Campus Road and Crooked Hill Road (CR 13) would have to be reconstructed to make room for the added lane, and the interchange with Pine Aire Drive (exit S3) would be completely rebuilt. A new interchange would also be constructed on the parkway between Pine Aire Drive and Campus Road, creating a junction with CR 100. Gerald Wolkoff thought that the discrepancy stemmed from his belief that transportation should be funded by the government, not from private sources, as his project would generate tax revenue for the government. ==Exit list==
