If any excavation is made across any public street, alley, or sidewalk, adequate crossings shall be maintained for vehicles and for pedestrians. If the street is not wide enough to hold the excavated material without using part of the adjacent sidewalk, a passageway at least one-half of the sidewalk width shall be maintained along such sidewalk line.
