This would be my guess as well. If you look closely at the top/sides of the tunnel in the photos, you can see what would appear to be equally spaced seams where the sections would butt together. Next time you're inside a tunnel without any cart traffic, maybe drive slowly through it and check it out from the inside. I'd like to do that myself..........'cept we're in OH.
