A Land Rover has crashed on the A14 causing its trailer which was full of soil to flip over on the dual carriageway near Ipswich.
The crash has closed lane one eastbound between Junctions 53, Ipswich North, and 54, Ipswich West.
There is approximately one mile of slow-moving traffic towards the incident at Sproughton and Washbrook.
Highways England and Suffolk Police are working to clear the soil but it could take several hours.
