The A141 road was closed between Mill Hill roundabout and the Manea junction last night after an accident involving a tractor and tailer and a Ford Fiesta.
The trailer overturned shedding its load of potatoes following the accident, which happened around 6.15pm.
Police, fire and ambulance attended the incident which also saw a lamp post damaged.
No-one was seriously hurt, but one driver was arrested on suspicion of dangerous driving. The road was re-opened at around 9pm after the road was cleared of potatoes.
