I could not remember exactly where was the old pier. There used to be both a passenger ferry pier and a vehicular pier there. The marker's location is just an approximation. The pier was gone when Aldrich Bay was filled up for redevelopment in early 1980's.
I have not been to Disco Bay for over 20 years. But I remember they had such a facility before they have highway access basically for residents' moving in or out. Yaumati Ferry used to have special arrangements with the developer for such ferry service. Don't know if the pier had been demolished or not. The marker above is just an approximate location. Correction welcome.
Any updates concerning if the pier is still there are welcomed as well.
