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 enters exit S1, a large modified cloverleaf interchange with the Long Island Expressway (Interstate 495 or I-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
