If your business goes under because of a temporary road closure, then the road closure just sped things along.
That's quite an cavalier attitude for a business like Old Florida Fish House that could see 1/2 or less of normal revenues. There are businesses on 30A that require the normal amount of tourist traffic to even cover expenses and make a living.

There are people staying on the east end of 30A who will never get on 98 to hit points west of the closure. And those who do may not visit anywhere from 395 east to the closure - Angelina's, Cafe Thirty-A, and a hundred other businesses on that stretch will suffer,
