Taxis are going to be banned from driving through parts of College Green.
From March 12th, taxi drivers coming from the Pearse Street, College Street or D'olier Street direction won't be able to drive past Trinity and on to Dame Street.
To ease congestion, between the hours of 7am and 10am, all taxis driving Southbound will have to turn on to Westmoreland Street.
There will be no restriction for those heading Northbound, and the ban will only apply in the morning time.
The National Transport Authority expects the measure to affect about 150 taxis each morning, but argues that it will "free up quite a bit of space".
Traffic congestion in the area has been chronic since the Luas Cross City line opened in December, and has already led to a number of Dublin Bus routes being diverted.
To ease taxi drivers' concerns, the Natinoal Transport Authory is going to allows cab drivers the freedrom to travel Northbound at night time from the bottom of Dawson Street along the Luas line on to Westmoreland Street.
It's hoped they will be able to pick up a large number of late night fares along that route.
Joe Heron, President of the Irish Taxi Drivers' Federation, admitted he was "shocked" by the announcement.
He suggested that officials "wait to see how much space is freed up when more bus services are removed, before removing taxis", arguing that "there may be no need to take taxis away from that route".
