Traffic changes to be implemented around Dublin's St Stephen's Green to facilitate Luas works will be permanent, according to Dublin City Council.
The changes, which will be introduced in late November, will allow traffic travelling down the east side of the green to turn right onto Merrion Row.
Brendan O'Brien, Head of Technical Services in the council's traffic division, has said the new system will take a lot of traffic out of Dawson Street.
Traffic currently has to travel down Dawson Street and then back up Kildare Street to access Merrion Row.
Traffic travelling along the south of the green will be allowed to turn right onto the west side of the green to access car parks at the Royal College of Surgeons and Stephen's Green Shopping Centre.
But traffic will still be unable to travel all around the green.
The traffic flow changes are being introduced to facilitate works on St Stephen's Green and Dawson Street for the Luas cross-city line.
This will link the green line, which stops at St Stephen's Green, with the red line on O'Connell Street and continue on to Broombridge in Cabra, where it will link with the Maynooth rail line.
