Sagtikos State Parkway

The Sagtikos State Parkway is a northsouth limited-access parkway in western Suffolk County that links the Southern State Parkway with the Northern State Parkway and continues north as the Sunken Meadow State Parkway toward Long Island Sound. Built in the mid-20th century as part of Long Islands parkway network, it remains one of the main cross-island connectors for drivers moving between the South Shore and North Shore.
Like other Long Island parkways, the Sagtikos is intended for passenger vehicles. Commercial trucks, tractor-trailers, and other oversized vehicles are generally prohibited, and drivers should always follow posted parkway restrictions and clearance warnings.

Notable Facts
- The Sagtikos forms one of Long Islands main northsouth parkway links, tying together the Southern State, Northern State, and Sunken Meadow parkway corridors.
- It is an important connection for drivers transferring between the Long Island Expressway and Long Islands state parkway system.
- Older parkway geometry, short merge areas, and heavy commuter traffic can make driving feel tighter here than on newer expressways, especially near Sunrise Highway and the LIE.
- There are no standard service plazas on the parkway itself, so plan fuel, food, and restroom stops off-route.
Traveler Tips
- Rush hours, summer beach traffic, incidents, and storm cleanup can all affect travel times on this corridor.
- Check 511NY or a current navigation app before you go for live traffic, construction, and closure information.
- If you are driving a rental truck, moving van, or towing equipment, confirm that your vehicle is allowed before using any Long Island parkway.
