I went down to take care of a few things on the boat in Whittier before the weekend. I checked the tunnel schedule and it said it was open until 11pm back to Anchorage. I was done by 10pm, and got to the tunnel at 10:10 and it was closed. I figured that they must have closed it early because there was no traffic, so I came back at 10:50 for the 11pm tunnel, but do dice. I went back to the boat and slept until the 6am tunnel (man it can blow nonstop in Whittier).
On my way out I stopped at the booth, and asked what time they closed, and if they are on summer hours, and he said they were and the last tunnel was at 11pm. When I told him I was there at both 10 and 11pm last night, he said, 'oh yea, we closed early last night for maintenance, didn't they tell you about that on the way in?' They did not happen to mention that to me. Upon hearing this he said 'oops, sorry about that'.
Something new to watch out for.
