When thaws or excessive moisture render the streets of this City or any sections of them, other than state highways, insufficient to bear the traffic thereon, or when such streets would be damaged or destroyed by heavy traffic during the period of thawing or excessive moisture, the maximum weight of vehicle and load, or the maximum speed, or both for vehicles, as prescribed by law shall be reduced in the following manner:
(a) The Director of Public Service shall prescribe such reduction which shall not be more than fifty percent (50%) of the limit otherwise permitted by law;
(b) The schedule of the reduction of maximum weights and speeds shall be filed, for the information of the public, in the office of the Director of Public Safety and in the office of the Chief of Police. The Chief of Police, at least one day before such reduction becomes effective, shall cause to be placed and retained on such streets, at both ends and at the points of intersections by principal roads, during the period of such reduced limitation of weight, speed or both, signs of substantial construction which shall conspicuously indicate the limitations of weight and speed which are allowed on the street and the date on which such limitations go into effect.
