Listen.
A neighborhood in New Orleans did this. Shut down traffic for a day to throw the thing a block party.
The city said, “haha guys ok, bet you won’t do it again.”
The next year they had an even bigger birthday party for the pot hole. Disrupted even more traffic. Local bakery donated cake.
The city caved and fixed the road.
If you cannot get things fixed by following the rules, be as bombastic as you need to be.
