National Highways said the crash has left the lorry wreckage hanging over a footpath below after it breached the safety barrier.
After the lorry is safely recovered, work will begin to repair the safety barrier, suggesting that the southbound carriageway will remain closed for some time.
Craig Sowden, Operations Manager for National Highways’ East region, advised drivers to avoid the area if they can.
‘This collision has left an HGV balancing precariously over a footpath used by members of the public below.
‘We have looked at all possible options but the only way to manage this situation safely is to close the carriageway.
‘We thank drivers for their patience and would advise them to allow extra time for their journeys.’
