Replace Gangway To Improve Visitor Access to the Historic Steam Tug Hercules
The new gangway replacing the existing gangway is roughly the same dimension, with only temporary impacts to the Bay during construction.
San Francisco Maritime National Historical Park proposes to correct visitor access and mechanical deficiencies in the existing gangway to the National Historic Landmark Steam Tug Hercules. This project constructs a 17,500-pound coated steel float; three 24-inch diameter, 80-foot long steel piles; an aluminum gangway and a 120 square foot transition platform from the steel float to the ship deck. The new gangway design automatically adjusts to changes in the tidal height that occur throughout the day, allowing for safe visitor access at all times. There will be a platform secured to the fan tail of the ship that is not permanent and still allows the steering mechanism to be viewable.
