No Exits or Entrances are numbered in the game, so they will be listed in order from where it begins after the Flatfish Place Access Road, to where it ends at the intersection of Topaz Street, Albany Avenue and San Juan Road. If you drive on the fast lane at the direction to the west, you will enter the Castle Tunnel. The Castle Tunnel runs under the Castle Gardens and continues to Union Drive West. Entering and exiting the tunnel will provide you an easy way to / from City Hall, Castle Garden City or other west-side areas served by the Union Drive West.
