Zion-Mount Carmel Highway Tunnel
The Top Picture shows the East Entrance to the Tunnel. Two-way traffic is not allowed now due to RVs and the like. A guard is posted at both ends of the Tunnel to ensure that this does not happens.
Notice the height restrictions posted on the entrance wall.
The Bottom Picture shows some of the total length of 1.1 miles of the tunnel.
If one looks to the middle far right of the picture you can see one of galleries (hole in the Mountain) that are used for both ventilation and light throughout the Tunnel.
Work on the Tunnel started in 1927 and it was completed in 1930 at a cost of a little more than half a million dollars. I wonder how much it would cost today?
I might add that the center-line of the road to the outside of the Pine Creek Canyon Mountain Wall is exactly 21 feet throughout the length of the Tunnel.
