The road was blocked as a result, but the Roads Management System (ROMANSE) for the area has since tweeted to say the motorway has been reopened.
The tweet read: ‘#M275 #Portsmouth - All lanes now REOPENED between A3 Mile End Road and J1/Tipner Lane, localised delays remain!’
A spokesman for ROMANSE said: ‘The Highways Agency vehicles - since the road has been closed - will lead the traffic back onto the motorway.’
However, severe delays remain, and motorists have been advised to steer clear of the area.
A Hampshire Constabulary said three vehicles were involved in the accident but only minor injuries were sustained although the two cars also overturned.
He said the recovery of the vehicles was expected from the outset to take some time, causing tailbacks.
It appears as though it will take a while for the recovery of the vehicles, so tailbacks are expectedHampshire Police
More than 20 emergency vehicles were reported to be at the scene.
At the time of the accident a Portsmouth City Council spokesman said: ‘Please avoid M275 northbound.
‘An overturned lorry has blocked all lanes just before Tipner junction.
‘There are significant delays already heading out of the city. Please use alternative routes.’
Traffic was backed up in Marketway and Anglesea Road.
Drivers were urged to use Winston Churchill Avenue to get through the city to use the Eastern Road as an alternative exit route.
