PC motherboard OEMs have done some interesting things with RGB LEDs and areas of the PCB with clear or no soldermask and copper removed from all layers to leave a translucent region of fiberglass that can be back-lit. This can achieve an effect similar to electroluminescent wire, and would be suitable for the tunnel segments of the map.
