The closure of Canberra Crescent is being extended to Friday 14 October.
Work has been progressing well this week, however a lot of services have been found in the area which has caused some delays.
The county council hopes that the work will be completed by the end of next week.
The closure is required for safe construction of the junction tie-in to the new Littlemoor Road.
Apologies for any inconvenience and disruption caused.
