A lorry crashed into a telegraph pole on a busy road in Diss.
The crash in Victoria Street, at about 8.30am, caused the telegraph pole to snap in half and power lines have been damaged.
The road was closed and stayed closed until the power lines were made safe.
Police were on the scene and contacted the power network company for assistance.
Officers turned drivers around near the Shell Garage on the road.
The traffic stretched along Park Road and Victoria Road from Dark Lane to Denmark Street.
There were also queues up Stuston Road and Sawmills Road.
Traffic is now able to pass after the road was closed for three hours.
