I was stuck there! I was flying out of Term C - that was backed up for about 45 minutes minimum. I asked my driver to go to Term D Arrivals, and walked up to D Departure, went through security, and walked to Term C (like a 8-12 minute walk).
That situation was a real mess. I didn't know there was a fire on the GCP. I thought it had to do with the snow. They really need to fix the entrance and exit to the airport.
