Whenever any person under the authority of this section places any obstruction in the public right-of-way or makes any excavation or alteration thereto for any purpose, it shall be the duty of such person or persons to keep the obstruction, excavation, or alteration properly safeguarded by substantial signs, barricades, and flagperson necessary and to make use of lighting, lighted lanterns, flashing lanterns, or other lights or flares from dusk to daylight in conformity with such regulations as may be specified by the Engineer. Whenever, in the opinion of the Engineer, the public safety is so endangered by such obstructions, excavations, or alterations as to require constant supervision to ensure that warning and traffic control devices are functional and that traffic is safely and properly routed around such barricades, the person or persons to whom a permit has been issued shall be responsible for furnishing a night watchperson for that purpose. Twenty-four hour notice shall be given before partial or complete closure of any travel lane in any street or alley. Should an emergency situation arise where a 24-hour notice is not feasible, every reasonable effort shall be made to notify the Engineer in advance of occupation of the right-of-way.
