The crosswalk going east/west across Covington at Waltham is marked by parallel lines and is unsigned. Much of the car traffic to Dicken school uses Covington. Many families live in walking distance east of Covington and use that crosswalk. Other crosswalks have been on Convington have been updated with high visibility markings/ bump outs/ and or signage. I would think that crosswalk should be similarily treated.
