An organisation representing city centre businesses has "strongly warned" plans to ban private cars from College Green will lead to "difficulties".
Private cars are currently permitted outside the hours of 7am and 7pm during weekdays. However, they will be banned on a 24/7 basis from May 29.
Dublin Town, formerly known as Dublin City BID which represents 2,500 businesses, said practical difficulties arise for businesses when vehicles are removed from a location, including "problems with deliveries, waste collection and sanitation, as well as access for utility providers and construction teams".
