Bayside Tunnel, is a highway tunnel servicing the highway running from Gant Bridge, through Tierra Robada, and into Bone County. It is modeled after the real life Waldo Tunnel in Marin City, California just north of the Golden Gate Bridge. It sits just to the northeast of the city of Bayside, cutting into the nearby hillside.
- Vortex (due to a spawn glitch, it rolls down the sand into the water when it comes into the player's sight).
Steal a car with 2 people in it, and do not let the passenger get out from the car while driving the car into the tunnel. Stop the car and let him out, once out you could run over him. It comes sounds from him like you are running over a pedestrian, but the person will not die. He will die later on.
