Justice Minister David Ford has agreed to open interface security gates at Northumberland Street on Sundays.
The development was agreed by people living around the interface at a meeting earlier this week and will commence on Christmas Day.
David Ford said: “This is a welcome step forward in providing increased access to the local community living on both sides of the gates.
“Within the last six months we have, in consultation with local communities, reached agreement to open gates in Alexandra Park, Newington Street and now Northumberland Street.
“These developments show what can be achieved through local engagement, consultation and improved community confidence.”
