The Chief of Police shall have authority to temporarily close any street, or portion thereof, when he shall deem such street to be unsafe or temporarily unsuitable for use for any reason. He shall cause suitable barriers and signs to be erected on said street, indicating that the same is closed to public travel. When any street or portion thereof shall have been closed to public travel, no person shall drive any vehicle upon or over said street except as the same may be necessary incidentally to any street repair or construction work being done in the area closed to public travel. No person shall move or interfere with any sign or barrier pursuant to this section without authority from the Chief of Police.
