Little Switzerland Tunnel
The tunnel was constructed in the 1950s in metamorphic rock, and for most of the length is unlined, supported only by rock bolts and chain link mesh. One section, about 100-ft long, required initial support by means of steel ribs, and has an 18-inch thick concrete liner for permanent support. It is 542 feet in length, 19 feet 8 inches in height.

My son and I pulled our bikes off the side of the road to get this shot. I carried the camera in a sweatshirt inside my tank bag for convenience, although it was a pain to stop and start, but it was worth it. I had entertained purchasing a camera mount for the handlebars but was told that a divorce from the wife and kids would follow; will work on it!
