Lieutenant Island Causeway is a narrow road that connects the mainland of Wellfleet to the small island of Lieutenant Island. The causeway crosses a salt marsh and offers views of the bay and the wildlife. However, the causeway is also prone to flooding during high tides and storms, making it impassable for vehicles and pedestrians. Visitors and residents of Lieutenant Island need to plan their trips carefully and check the tide charts before crossing the causeway.
