Motorists have faced long delays in and around Westridge Cross due to the closure, which has resulted in traffic diverting via Marlborough Road.
Island Roads say that Southern Water have informed them that the road will reopen this evening. Docklands Traffic Management, acting on behalf of the water supplier, say the closure is likely to be lifted at around 19:00.
Southern Water have said a broken tarmac plant has resulted in the delay in opening Great Preston Road.
In response to an enquiry by Island Echo, a spokesperson for Southern Water has said:
“We are sorry to hear that the closure of Great Preston road is causing disruption.
“Our team are working hard to resolve the issue as quickly as possible following our vital repair works on a burst main on Saturday August 26. The force of the burst lifted the carriageway, causing extensive damage.
“In order to reopen the road as quickly as possible we were scheduled to carry out a temporary reinstatement today (Friday 9 September). However, the tarmac plant on the island has broken down, delaying our work. We will provide an update on when this work will take place, which we hope will be as quickly as possible”.

With regards Ashey Road, which also suffered a burst water main recently, the spokesperson said:
“We have carried out a temporary reinstatement in Ashey Road to allow the road to reopen. Permanent reinstatements have to be agreed with the HA (Island Roads), who will use ground penetrating radar to quantify the extent of the damage and advise us of the full resurfacing requirements.
“Once we have this information, we will be able to begin the permanent reinstatements and will keep our customers advised of these works.
“We’d like to thank customers for their patience and understanding.”
