The current wet weather being experienced as a result of "Storm Abigail" has delayed plans to introduce temporary traffic lights at Pennyburn roundabout in Derry.
The lights had been due to come into operation tomorrow morning but TransportNI has said this has been put on hold until conditions improve enough for an anti-skid surface to be laid.
A spokesperson said the work would be completed when weather permits
When operational, the signals (pictured) will operate on a part-time basis initially and will be work between the hours of 7.30am and 9.15am every day.
