The drive

Dune Road runs along the barrier beach of Long Island's South Shore, with the ocean and dunes on one side and the bay on the other. This drive starts at Westhampton Beach and heads east for 7.2 miles to the Ponquogue Bridge, which crosses back to Hampton Bays.

It is a flat, gentle road with beach houses along it; its character comes from the setting, a thin strip of land between two bodies of water.

That setting is also its weakness. Tidal flooding and storm overwash have repeatedly closed Dune Road, including the stretch near the Ponquogue Bridge, and Southampton Town has declared emergencies to close it.

Good to know

  • Storms and high tides flood the road; the town closes it and usually reopens it once the water drops.
  • The drive ends at the Ponquogue Bridge, which also floods in storm tides.

Open all year, weather permitting. Roads close for snow, fire, storms and repairs: before you set off, check Southampton Town.
