Eversource said it was probably heavy snow and winds that caused the line to come down. Crews are rising to some 200 feet to replace the line.
“The height is a challenge. Crossing the river is a challenge. And so we’re going about that in a very methodical way. We have a boat to pull us across the river,” said Eversource spokesman Frank Poirot.
Eversource says it is hoping to have that line repaired by the end of the day on Friday.
