A rolled over lorry is currently blocking all three lanes of the M11 northbound.
Shortly before 1pm this afternoon the HGV tipped over while coming around the corner of a slip road of junction 6 on the M11 and junction 27 of the M25.
One man who was driving several cars back from the lorry when the crash happened said: "I was about six rows back when traffic came to a halt.
"The lorry looked to be full of recycled plastic.
"Traffic escaped through the hard shoulder because the lorry covers all three lanes.
"The lorry driver was sitting up on the railings getting first aid.
"Significant blood was coming from his arm but he seemed ok."
A Tweet from Essex police confirmed that the M11 would be closed for "some considerable time" and that all traffic would be diverted on to the M25.
