The Southern State Parkway is a core east–west artery on Long Island’s South Shore. Opened in stages beginning in the 1920s–30s as part of Robert Moses’ parkway system, it runs from the Cross Island Parkway in Queens through Nassau County and into Suffolk County, where it transitions to the Heckscher State Parkway approaching Heckscher State Park. Like other parkways in the region, it is passenger-cars only (no trucks/commercial vehicles) and is known for its classic stone overpasses, tight curves, and heavy commuter volumes.

Notes:

Notable Facts

  • Designed as a scenic, limited-access parkway for passenger cars – part of Robert Moses’ vision for Long Island mobility and recreation access.
  • Shares the South Shore role with Sunrise Highway (NY-27) but provides a parkway-only alternative with key beach connectors (Meadowbrook/Wantagh).
  • Legacy design elements (stone bridges, tighter curves) contribute to its distinct look – and to modern operational challenges during peak traffic.
