Tunnel

I drive past this tunnel every morning on my way to work and meant to take some photos of it.

As the traffic was nearly non-existent i managed to stop by the side of the road and take some photos of it. Can anyone guess where it is?

I did submit another tonight but decided this was probable the better option. If you would like to see the other option then click the link below...
