end of the road

I dreamt that I was going to the beach with my dad. We took Hwy 99. There has always been a sign there that has two routes, one that goes through town and one that circumvents it. I've always gone through the town, but decide for some reason to take the other route this time. It lead to a hangar and it seemed the road stopped right at the building. I figured due to the size of the doors on the hangar, you must be able to drive through it. I went to the building and checked with the people. A tall blond woman said yes, you do drive through and pointed me to another large door on the other side of the inside of the building. My dad was talking to someone else in the building as I went to inspect the door and see what was on the other side. I opened it and the pavement only went a few feet and perfectly ended...  and there was a hedge that you couldn't pass. So you couldn't really drive through. It was the end of the road and would have to go back and start again.
