Neighborhoods in the Elm Street area are still without electricity after a car hit a utility pole near South and Elm Streets earlier this evening.
As of press time, the box (which was on a double pole) was on the sidewalk. NStar's website reports 170 Medfield homes are without electricity, and they are working on the problem.
