The northbound carriageway of the A12 has reopened following a multi-vehicle collision between J24 at Kelvedon and J25 at Marks Tey in Essex.
All emergency services attended the incident.
The collision has caused long delays, with traffic congestion for more than seven miles south of J24, all the way back to junction 21 at Witham.
National Highways suggested a diversion, recommending exiting the A12 Northbound at J19, at Boreham, and following the A130 to Chelmsford and the A130/A131/B1008 roundabout.
From here, take the third exit onto the A131, and proceed to the A120 at Panners Interchange. At the interchange follow the A120 for Colchester.
Continue on the A120 until you reach Marks Tey, and and rejoin the A12 at J25.
