The city is making progress on adding a traffic signal at Burroughs and Centre streets. The construction is expected to be completed this fall or winter, according to the Boston Transportation Department. The intersection, at the heart of JP's Centre/South district, will have buttons for pedestrians to activate the lights. The signals will be on poles rising out of the sidewalk and will not hang over the middle of the street, according to Transportation Department plans. The impetus for the new lights came from a neighborhood request, according to Tracey Ganiatsos, spokesperson for the city department.
