MOTORISTS are facing 10 days of tailbacks as emergency repair works take place on a collapsed sewer.
Southern Water will be working 24-hours-a-day to complete the repairs along the A32, Fareham Road in Gosport, near Vector Aerospace from November 14.
But it will mean the closure of the southbound lane, which is likely to cause severe delays.
The cause of the collapse on Tuesday is not yet known and is currently being investigated.
And a temporary overland sewer has been laid to ensure customers can still use their water supply while the repairs are carried out.
Maria Harrison, a spokeswoman for Southern Water, said: ‘We know it’s a busy road, but we aren’t starting work immediately because we don’t want to, it’s because we have been working closely with the county council’s highways department and they have advised us we can’t start until the 14th.’
Cllr Mark Hook, leader of Gosport Borough Council, said: ‘It’s going to be chaos and we can just ask for the co-operation of the travelling public. It’s unfortunate timing, but when you’ve got a situation like this, it has to be dealt with.
‘I’m grateful they will be working 24-hours-a-day to get it done.’
The southbound road will be closed to allow teams to dig down four yards to the 18in sewer pipe.
There will either be stop/go signs or traffic lights to manage the flow of vehicles both ways.
The repair is expected to be completed by November 23.
Councillor Mel Kendal, in charge of transport matters at Hampshire County Council, said: ‘We are aware that the need for this work coincides with other schemes in the area affecting traffic movements but the repairs that are needed are essential and cannot wait until the other works are finished first.
‘We are pleased that Southern Water is acting so quickly to rectify the situation and is employing engineers to work round-the-clock so that any disruption is kept to as few days as possible.’
