One of our Pennsylvania Turnpike tunnels which originally was suppose to be a railroad tunnel near Harrisburg. The far tunnel was the railroad tunnel never completed and sat for 50 years B4 the turnpike came along and used it as the first super highway in America.
The square stones in the foreground have been laying here since 1883-1885 when the railroad was cutting them to build their tunnel now used as a turnpike tunnel.

In a different part of the route shows the route 219 north of Somerset cutting across the old railroad right of way. (look at the other side in the center of this photo to see the silhouette of the railroad grade. The day had to be just right to get this shot.

Above. this is the valley seen in the previous photo above. The double mountain makes it hard for snakes to wonder out of this valley. Workers at the tunnels say that the snakes love the warm stair wells so it isn't uncommon to find them at the tunnels when they come to work. Also in the previous photo, I had gotten there a week late as one of the workers explained that the lights and power grid short circuited once or twice as upon investigating when this happens is to check to see if a rattle snake isn't fried atop the power lines in the enclosed power step down station off to the left. .
