Dublin City Council is extending the pedestrian trial of the Grafton Street area in the city until the end of August.
The council said it has received "extremely positive feedback" following the first three weekends of the trial.
Each of the locations will be closed to traffic from 11am to 11pm on Saturdays and Sundays.
The locations includes Anne Street South from the junction of Dawson Street; Duke Street from the junction of Dawson Street; South William Street from the Brown Thomas car park exit to Chatham Row; Drury Street from Fade Street to the Drury Street car park, and Dame Court from Exchequer Street.
Dublin Chamber of Commerce has called on the council to extend the trial to weekdays.
Dublin City Council has also decided that from next week, seven-day permissions for outdoor tables and chairs will be granted at a number of locations.
It said the measures are being taken to support the economic recovery of the city by providing more space for pedestrians during weekends to encourage people to return for shopping and to make use of the many cafes and restaurants in the area and enjoy the city centre.
Access to car parks in the area will continue to be maintained at all times, the council said, and all car parks are open.
Access for emergency vehicles will be maintained at all times.
