You have an intrusive "l" in front of the target URL in your first link. Corrected version:

Re: Longest Tunnel

I am sure they thought of everything, but I heard no mention of the possible and likely

differential atmospheric pressure from one side of the mountain to the other;it may in

fact be self ventilating at times and resisting ventilation at other times.

Just curious of the effects of weather on the ventilation systems?

Any opinions on this matter?
