A bus lane in Belfast's Titanic Quarter has been suspended after motorists complained of tailbacks on the Queen's and Sydenham roads after its introduction.
The bus lanes were phased in to facilitate the city's new glider buses, due to start running on 3 September.
However, the Department for Infrastructure (DfI) says the city-bound bus lane on Sydenham Road could be suspended for up to a year.
Ciarán De Búrca, from the DfI, says it could be six to 12 months before the bus lane reopens.
An extra lane in the area has been proposed to allow the bus lane to be reinstated in the future, he says.
