Repairs to traffic lights at a major Preston junction are being forced to continue for a further few days.
Lancashire County Council said its engineers had not yet been able to restore the signals at the London Road, New Hall Lane and Queen Street junctions.
Motorists have been left frustrated by temporary lights causing tailbacks at the key route in and out of the city centre.
Timings for the temporary lights had initially been configured wrongly.
Now engineers are to be given more time to fix the problem – caused by an electrical fault. It had been due to be fixed by Friday (16 June).

Highways group manager Daniel Herbert said: “We apologise for the inconvenience caused during this emergency repair work at a major junction.
“This is a busy junction and we know that it has significantly affected this area, as well as other parts of the city centre.
“Please allow more time for journeys in this area, which have been disrupted, especially at peak times. We know that this is likely to affect the rush hour on Monday.
“We are doing everything that we can to fix it as soon as possible. Work is already taking place, and will be continuing over the weekend, to try to fix the fault by early next week.”
