Part of the A14 is currently blocked after a three-vehicle crash.
Officers were called to the eastbound carriageway near the Tuddenham turn-off at about 8.30am.
A spokesman for Suffolk police said a lorry, van and car are involved in the crash.
There has been no reported injuries but the carriageway is completely blocked, the spokesman said.
It comes after the A14 was closed this morning near Bury St Edmunds due to overrunning roadworks.
According to the AA Traffic Map there are long delays in the area.
