Alcatraz Wharf

The steamer towed officers, prisoners and food and water supplies to island between 1867 and 1886, landing at the dock twice daily before being replaced.

The Sally Port led from the dock to the original citadel on Alcatraz along a walkway, 12 feet (3.7 m) above a dry moat.

Today the dock meets visitors to the museum on the island and is served by boat trips daily.

In the mid-1880s, work on the wharf area was undertaken to repair it and to create coal sheds and a boathouse.

The retrofit to the existing wharf and its facilities consisted of concrete demolition, excavation, and installation of tiebacks.
