Pictures are quite old as I visited over a year ago but thought I'd share 
The tunnel lies at the side of the road close to Glen Helen, the same road it was created to build. From the road it is hard to see most of the year, being covered by undergrowth. The quarry at the other side of the tunnel is a lot smaller than I expected, seeing as the tunnel is quite long with plenty of turns and twists.
