Eversource is conducting aerial inspections of vegetation growing near its high-voltage electric lines. This semiannual inspection is being done from Thursday through the end of next week. Utility officials say this is important for service reliability. The inspections will be from 7am to 4pm, weather permitting. A blue and grey helicopter, Tail # N1431W, and a blue and white chopper, Tail #N411DD, will be used. The aerial inspections are being done in Bethel, Bethlehem, Brookfield, Danbury, New Milford, Newtown, Oxford, Redding, Ridgefield, Roxbury, Weston, Wilton, Woodbury, and 73 other municipalities.
