First post here, so hopefully this has gone to the right place! When I added the tunnels on the A538 under the runway at Manchester Airport, I basically drew them in roughly as a constant-ish radius curve. That's certainly what they feel like to drive through. I can't see that too many people would be losing sleep if there a few metres out. It obviously gets a little more complex if there's junctions and curves in different directions, but I still agree that it's best initially if we can get it on the map, then worry about the precise route.
