is there a way of making a high density avenue with a streetcar avenue where the street car part of the road can be raised up and down whilst the road remained at ground level. The reason I ask is because in one of my cities, I end my road with a T junction but continue the street car track (essentially creates a 4th direction of traffic stoppages). Therefore if I could lower the streetcar portion or create a tunnel with the streetcar part it could help traffic problems notorious for this type of road
Thanks
