(A) City personnel or contractors, while repairing or improving or repairing lines or other utility facilities in the streets, are authorized as necessary, subject to control of the Chief of the Traffic Division, to close any street or section thereof to traffic during such repair, maintenance, or construction. In exercising such authority, such person shall erect or cause to be erected proper control devices and barricades to warn and notify the public that the street has been closed to traffic.
(B) When any street has been closed to traffic under the provisions of division (A) above, and traffic-control devices or barricades have been erected, no person shall drive any vehicle through, under, over, or around such traffic-control devices or barricades or otherwise enter the closed area. This division shall not apply to persons while engaged in such construction, maintenance, and repair or to persons entering therein for the protection of lives or property. Persons having their places of residence or places of business within the closed area may travel, when possible to do so, through the area at their own risk.
(C) Whenever construction, repair, or maintenance of any street or utility line or facility is being performed under traffic, the city personnel, contractor or utility company concerned shall erect or cause to be erected traffic-control devices to warn and guide the public. Every person using such street shall obey all signs, signals, markings, flagpersons, or other traffic-control devices which are placed to regulate, control, and guide traffic through the construction or maintenance area.
