The Pennsylvania Turnpike

This shot was taken by my mother, as I was driving. I wanted a shot of the turnpike. There are a couple places where you go through a tunnel.
The Pennsylvania Turnpike began in 1937 and was completed in 1956. When the first section was completed in 1940, it was the first modern limited access highway. The first section was completed using parts of the Southern Pennsylvania railraod and 6 of the 7 tunnels used were built for that railroad (except for this one). It was known as the "Tunnel Highway".

I would have to say that it is a pretty nice stretch of highway and considering the mountains you are going through, the grading is not that bad.
