The A347, New Road, in West Parley has been closed since the beginning of March for Dorset County Council to repair the road.
The road will reopen to cars, vans and buses this afternoon (18 March) ahead of the evening rush hour. HGVs will continue to be diverted until 3 July due to narrow lanes on Ensbury Bridge, which is being repaired and repainted.
The original timetable for the road closure was three weeks.
Cllr John Wilson, local councillor and Chairman of the county council, said:
“I am delighted that we have been able to finish this work ahead of schedule this is partly due to the weather and the determination of our staff.
“I’d like to express my gratitude local residents and businesses for their patience and their forbearance during this time.”
The repair was needed because tests showed that the structure of the road was severely damaged. The county council employed specialists, Stabilised Pavements Ltd, who recycled material in situ and added bulking and binding elements to give the road a new lease of life.
