In the Daily Herald today it stated that the reason for the blockage were "French Quarter residents raised several complaints. Chief among them was the absence of a Gendarmerie station in French Quarter since Hurricane Irma and the fact there is still no post office, meaning the elderly and other citizens still have to go to Marigot. Other issues include unemployment, the high cost of living, high water bills, restrictions imposed at Le Galion by Conservatoire du Littoral, and poor Internet coverage."
