South Moger Avenue, one of Mount Kisco's main retail roadways, was closed for part of Tuesday afternoon.
Mount Kisco Fire Chief Tom Jackson said the department received a call at around 11:10 a.m. about a smell of smoke and flickering lights at the People's United Bank on South Moger Avenue.
After the call, firefighters then discovered smoke coming from a utility manhole in front of Sleepy's and a decision was made to evacuate nearby businesses.
While workers have been let back inside for now, Con Ed is checking the feeder cable underground, Jackson said. A compromised feeder cable would result in cutting the power until it's fixed.
