Infoview overlay during road & transit construction

[AsciiOfTheNorth]

Terrain level is shown by default when building canals already and it's kinda weird that you can't do something like this when building roads.
I don't even need the full infoview menu, but some sort of terrain view is needed to build pretty roads in a decent amount of time.

Also I get the consoles are limited, especially my PS4, but it seems like a canal would be more intensive than a road to build. Correct me if I'm wrong tho.
