Queues due to the closure are stretching several miles, with traffic now backed up past Eastleigh near to Junction 11 for Winchester on the M3 and to Redbridge on the M271.

Traffic monitoring service, TomTom, estimates motorists will be queuing for at least 50 minutes to reach the junction for the M27.

There are delays of over half an hour on the M3/M27 spur - as the road is taken down to two lanes past Rownhams services.

National Highways has estimated the road may not reopen until 2030 this evening (Friday 11 August).

Traffic is backed up through Romsey and out towards Winchester - with delays upwards of 60 minutes from the city towards Romsey.

A significant number of roads are now congested in Southampton, with queues of 45 minutes reported on several routes.
