10-2-4: INTERFERENCE WITH TRAFFIC:
Any work done under a permit provided for in section 10-2-1 of this chapter shall be performed in such a manner as to cause the least possible interference with the movement of traffic. On main thoroughfares, there shall be at all times sufficient traffic lanes open to permit a substantially normal traffic flow; otherwise the work shall be confined to the hours between nine o'clock (9:00) A.M. and four o'clock (4:00) P.M. or between twelve o'clock (12:00) midnight and seven o'clock (7:00) A.M. In the event the work is of an emergency nature, the city manager may authorize work during other hours under such conditions as the city manager shall determine appropriate. (2007 Code § 41-49)
