A single car crash closed Berkshire Road in Newtown on Sunday afternoon for about two hours.  Firefighters and paramedics responded to a report of a vehicle off the roadway, with the driver unconscious.  A nurse on the scene reported that she was unable to find the pulse of the elderly man.  Police were first on scene and said the 73-year-old was unconscious, but had a pulse.  The car was headed east, but continued straight on a curve and crashed into a stone wall before stopping.  The driver was transported to the hospital.  The road was closed while police conducted an investigation, and while a wrecker responded. Frontier and Eversource were also notified due to damage to a utility pole.
