Here I have an avenue, that I wish to head east past the railway track where I plan to create a huge residential area.
But I do not wish to disturb the railway track, nor go over it. Is it possible for me to create a tunnel? I tried to drag, but it only gives me the option to go over the hill.
Here is an angle from the other side:
And here is where I wish the tunnel to go.
Any help please?
Thanks.
