As of this writing the Whittier Tunnel has been finished and in use for some time. However, I only got around to using it when I was home for the winter break, and I must say it was an interesting experience. Since the tunnel is shared with a train, there are only certain times you can drive through it. I think the last window of opportunity to leave Whittier through the tunnel is at 4:30 PM. Speaking of Whittier, there must be some sort of business agreement which was pushed through in secret in order to justify the construction of this tunnel, as Whittier itself is very small and does not by appearances have a healthy economy.
