Are you going there from the Manhattan or Brooklyn side ?i guess in uber you can set the address as Brooklyn Bridge Stop or you can go to the Chambers St. Stop if you are going there from Manhattan.
You can go to City Hall / Brooklyn Bridge Side / Chamber St Station and from there it is walkable distance only.
Closest from Manhattan and from the very start of the walkway is Centre St right after the New York city Comptroller building
South St
Ill be coming from manhattan
South Street Two bridges side
