Sunday Bridges - Tunnel through the Blue Ridge

When Sue and I drove through the Great Smokey Mountains on that foggy Monday last month, we passed through a number of short tunnels.  As we approached the outlet the fog filled the air with a soft glow.  As we cleared the exit the trees and pavement emerged from the fog into view again.  It was a pleasant sensation.

I hope it is proper to post a tunnel on bridge Sunday.  To my thinking, a tunnel is a bridge pulled inside out.
