On Facebook, motorists shared the scene was "carnage" as traffic built up as a result of the overturned lorry, with some reporting being stuck in traffic for several hours.
Stuart Copple said; "Saw that lorry overturned this morning, it looked dreadful, but hope the man is ok."

Jayne Ward shared she was caught in delays for more than two hours.
She said: I've literally been sat in this for over two hours as I didn’t see this had happened."
