Movie Filmed at Abandoned Penna Tpk Tunnels

[CDL holder]

I recently saw some activity on the abandoned portion of the Penna Tpk near the Allegheny tunnel east of Somerset. Today I was checking out The Road at IMDB and saw that it's in post production now but scenes were shot in the abandoned tunnels and at other western PA locations. I wondered what was going on and maybe it was the film crews?

I read the book by Cormac McCarthy and will love seeing this movie when it comes out 26 November 2008.
