Whenever the condition of any city street, by reason of rain, snow, climatic or other condition, is such that it will be seriously damaged or destroyed unless the operation of vehicles thereon is prohibited or restricted or it would be dangerous to permit traffic thereon, the city council may impose limits as to weight or speed of vehicles thereof, or any other restriction that may be deemed necessary, or may close such street to all vehicles or any class of vehicles for any period of time the city council may determine by resolution. Such resolution shall be published in one issue of the official newspaper prior to the effective date of such restriction or closure; provided, however, that in cases of emergency, the street superintendent shall have the authority to make restrictions effective immediately, in which event he shall make a report thereof to the city council at its next regular meeting; provided, further, that no such restriction, placed upon streets forming a part of the route of any state highway is effective until first approved in writing by the director of highways of the state of Washington.
