It isn't necessary this late in the winter season the snow is melted and lower but a major snowstorm or two between now and April and the walk light button would be blocked by plowed snow.Then it might be necesssary as a matter of pedestrian convenience and safety in needing to cross a sometimes busy intersection but not able to push the white walk signal to give the ok to cross the street when the traffic light is green for traffic to cross in the same direction.
