Traffic restrictions on College Green are set to discommode bus and taxi commuters until next year.
Dublin City Council is warning the disruption will continue for longer than planned because of delays to planning hearings about the redesign of the area.
There are 100 fewer buses serving College Green during rush hour and taxis have been banned from travelling southbound during peak times.
The decision was made to deal with the chronic gridlock which followed the opening of the Luas Green Line extension last December.
But the head of traffic in Dublin City Council has warned the measures could stay in place until 2019.
That's because hearings have been delayed on the proposed pedestrianisation of the College Green.
They were only supposed to take a few days, but due to the complexity of the revamp, the hearings continued for more than half of March.
Brendan Kenny says it means a decision from An Bord Pleanala isn't expected 'realistically until at August or September.'
