Credit: Michael Dinan Parts of Locust Avenue and Main Street will be closed at night as part of a three-week project slated for April, officials say. Eversource’s work on Locust from the area of Forest up to Main, and then down Main to East Avenue, is expected to start around 9 p.m. and continue until about 5 a.m., according to Project Manager Charlie Frangis. “Since it’s at night it will be less of an imposition but we just want to detour traffic, including trucks, either through or around the construction site,” Frangis told members of the Police Commission at their regular meeting, held Jan. 20 via videoconference.
