The only thing I can think of is that is a one way street................
But still there should be some way to get out if it is a residential street. Blocking it off completely except for a real emergency is not acceptable.
The more I look at this the more it looks like very poor planning by the city.
Like I said, I don't agree with the driving on through but I don't think she was being that unreasonable. Bosses are not understanding about the "my driveway was blocked off because of a street fair and there was no way out" excuse.
Heck the boss was not very understanding about the "water main broke and the street is now a river" excuse.
