The Arizona Republic and the local news channels focused for days on how dark the lighting was for drivers entering the tunnel immediately after driving from the bright Phoenix sunlight.
Weeks had passed and ADOT realized all they needed to do was to tile the walls of the tunnel so reflective light would rectify the situation and more evenly light the tunnel-yet none of the local media talked about the solution. Initially, the walls were concrete and they absorbed so much light that it created a difficult adjustment for drivers entering and leaving the tunnel.
