Traffic is set to be flowing again at a busy junction closed after a sewer collapse.
Anglia Water said it was "a complicated repair" that would mean closing the roads for several weeks and diverting traffic away from the pinch point.
On Wednesday a spokesman said the roads would reopen by the end of Sunday (May 22).
She said: "We needed to dig down to expose the pipe to enable us to repair it, however that was complicated as there were a number of other utility assets in the area we were working in.
"Now that are finalising the completion of the repair we will be relaying the ground and road surface to enable to us safely reopen the road by the end of Sunday."
The water company said it understood the works had caused inconvenience and thanked everyone for their patience.
