Some bus routes may be banned from Dublin's College Green to make way for the new Luas Cross City line.
A transport study proposed that cars and taxis should be excluded from the area, and there is already a 12-hour ban on regular vehicles using the busy city centre thoroughfare.
However now it has emerged that buses may also be barred from College Green.
Dublin City Council have said that the issue concerns routes that used to go through College Green, but have been diverted already due to Luas works.
Chief Executive Owen Keegan says some buses cannot be accommodated on their traditional routes or alternatives.
Speaking to Pat Kenny this morning, he explained "the issue really concerns the buses that are currently diverted.
"They're buses like the 46A that used to turn left at the bottom of Dawson Street, and [travelled] along Nassau Street, Suffolk Street, down Church Lane and on to College Green".
He added that the 46A is one of the busiest bus routes in the city, and a number of other busy routes have also been impacted.
However he reassured bus users that the majority of services currently travelling College Green will remain unchanged.
