A helicopter will fly over dozens of Connecticut cities and towns in the coming days as Eversource inspects its equipment.

The semiannual inspection is meant to check for any emerging vegetation and equipment issues that may threaten electric reliability, according to a press release from Eversource.

The helicopter will fly over the company’s high-voltage electrical equipment on the transmission line in Bethel, Brookfield, Danbury, New Milford, Newtown, Redding, Ridgefield, Roxbury, Washington and several other towns.

Aerial inspections will be held from 8 a.m. to 4 p.m. through Thursday, weather permitting.
