This will make a tunnel from Dragons Crown Valley, and Erithwood Valley. Connecting the huge northern Valley, with the southern road network. It have it exit in the hills between Dragons Crown and Erithwood.
tunnel starts : [19:50:38] Your current coordinates are: x: 2206 y: 1587 tunnel ends : [18:20:07] Your current coordinates are: x: 2206 y: 1517
Total 70 tiles with tunnel 2 tiles wide, and with reinforcement both sides.
What is the height of the tunnel floor above the waterline? I'm thinking of building a tunnel that would cross it, and I wouldnt want to build it too high or too low that a bridge couldnt be used or intersection
