As tunnels are partly transparent, would it be possible to make Highway to be inside the tunnel. After all the rules are set up so that units get benefit from both of them simultaneously (tunnel allows Earthly units to travel on those tiles at all, Highway sets the higher speed).
Of course, if we follow that logic through, then also Roads should appear inside tunnels, so they would need reworking.
