The permanent traffic ban through College Green came into effect today.
Previously private cars were permitted outside the hours of 7am and 7pm during weekdays. However, they are now banned on a 24/7 basis.
Local access to the Dame Street and College Green areas and to the Bank of Ireland and Fosters place will be maintained for general traffic but they cannot exit using the Bus Gate. Business representative group Dublin Town had previously voiced concerns about access, saying the ban will lead to "difficulties".
