A few weeks ago, a reader sent in a picture of an intersection on Katonah Avenue in the Bronx, which DOT repaved and striped with a double-yellow line — but not crosswalks. For more than six weeks, residents crossed this neighborhood artery without painted markings, which had parents at P.S. 19 especially worried.

Our tipster recently wrote back with good news: Two days after we posted about the missing crosswalks, DOT crews were out on Katonah Avenue, putting high-visibility markings in place.
