The A140 near Little Stonham has reopened after a lorry crashed into a telegraph pole yesterday cutting the power to more than 350 homes.
The road was closed in both directions for 13 hours, from 4pm yesterday to 5am this morning, while the vehicle was recovered.
Fire crews from Needham Market and Debenham rushed to the scene at 10.45am yesterday to find a Scania articulated lorry on its side in a field with 11,000 volt cables attached to the vehicle.
The high voltage cables meant the driver was trapped in the lorry cab.
Engineers from UK Power Networks attended the scene and once power was confirmed as isolated, crews released the driver who was taken to Ipswich hospital by ambulance with facial injuries.
Electricity to 376 homes was interupted due to the crash although power was restored to 366 of these within the hour.
Power was restored to the remaining properties by 9.30pm on Wednesday.
