John B. Whealton Memorial Causeway

The John B. Whealton Memorial Causeway connects Virginia's mainland to Chincoteague Island and consists of five bridge sections spanning multiple water channels. The structure features four fixed bridges and one drawbridge following State Route 175, with a single lane in each direction.

State approval came in September 1919, leading to construction with a budget of 144,000 dollars and opening on November 15, 1922. The bridge was built to connect the isolated island to the mainland and enable access to its resources and communities.

The causeway serves as the main passage to Chincoteague Island's famous annual pony swim, an event that draws visitors from across the region. It connects people with the wildlife refuge and its distinctive animal populations in a way that shapes the island's identity.

Driving across the causeway is straightforward and well marked, though the drawbridge occasionally rises to allow boats through. Visitors should stay focused on the road and drive slowly, especially when the drawbridge is in operation.

While crossing, travelers can spot NASA Wallops Flight Facility's satellite dishes and research equipment behind security fencing. This aerospace facility remains largely hidden but offers a brief glimpse into the scientific activity happening in the area.
