Whenever any ordinance designates and describes a through street, there shall be a stop sign on each and every street intersecting such through street or intersecting portion thereof described and designated as such by any ordinance unless traffic at any such intersection is controlled at all times by traffic control signals; provided, however, that at the intersection of two (2) such through streets or at the intersection of a through street and a heavy traffic street not so designated, stop signs shall be erected at the approaches of either of said streets.
