Water firm bosses have said a £1.2m project that has caused frustrating delays for motorists has overrun and they don't know when work will finish.
South East Water installed temporary traffic lights on the Windsor Road near Bray in August as part of work to install a new water main.
The lights have caused some peak-time tailbacks stretching from the roundabout to Stafferton Way.
Work was due to finish by November 1.
The firm's delivery manager Chris Love said: "Since we began other utilities have had to carry out emergency work, which has required us to pull off the road twice.
“Unfortunately this has had a knock-on effect to our programme."
He added the water mains work will be staggered over the coming months but was unable to give a completion date.
The water company is liaising with the Royal Borough.
