As a locator, this is laughable. Legally, MU Tickets have a lifetime of 14 days; realistically, I've marked tickets that were years old and the work had yet to begin, they just keep calling in updates to extend the ticket life.Considering Miss Utility Tickets have a lifetime of 14 business days, work should start very soon.
However, this does mean that if they really wanted to, the work could begin on 12/26 at 7AM.
