Bridges, cars flying vertical up and down


I have made a bridge and now happens crazy things , see this video!AjzVTRQseSomj3ScmsM4QWjb_0n9?e=DZ7lsS

It seems that one street under the bridge is not connected and the cars floating at this point up. The second smaller street under the bridge is not involved. Any idea to fux this?

An other point is the ugly road texture under the bridge, is there any way to delete this?

you’re probably better off moving this question to the SDK subforum.

Ok thanks, I made also a thread there. because I don’t know to move. Maybe someone can delete this thread
