A. Where any sidewalk or portion thereof is in the course of repair or construction, or is so defective as to constitute a hazard, the contractor making such repairs, or the owner or agent of the property abutting upon such sidewalk, shall cause a barricade to be erected to safeguard against accidents. Where there is not sufficient light to reveal such barricade, there shall be suitable warning lights placed thereon, which shall be in operation from dusk to daylight.
B. Such barricade shall be maintained so long as required, but no longer, and shall not be interfered with, changed or removed by any person other than the contractor, owner or agent. (1960 Compilation § 14-110)
