I am working on DTW airport and i need a little help.
The airport ground traffic connects the south terminal and norh terminal by going under the taxiway F , Rwy 9L-27R and taxiway V.
How can i make a tunnel under the taxiway`s and runway? or
Is it possible to add a bridge in special where the runway crosses?
In the same time i want the airport traffic to stay in the tunnel and not popping up like in this video:
Thanks in advanced
