The A14 has been re-opened by police after an earlier accident.
A Landrover Defender flipped on the eastbound carriageway between Nacton and Seven Hills.
No other vehicle was involved in the crash.
The male driver was unhurt but shaken by the incident, which happened at 3.39pm today.
The car blocked the fast lane and part of the slow lane, and Suffolk Constabulary temporarily closed the A14 while recovery took place.
Fire and ambulance crews also attended the scene.
