Ferry
The Ferry is a major link between Portland and Staunton Island during the construction of the Callahan Bridge in Grand Theft Auto: Liberty City Stories. Only certain vehicles can enter the yellow marker to the other island. Naturally, the player can just drive over the Callahan Bridge construction. Later on in the game, the ferry is threatened to be closed for more work on the Porter Tunnel. However this never happens, until Grand Theft Auto III (set three years later).
