(b) The director of transportation services, upon the director’s own initiative, may conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and if the director thereupon finds that such structure cannot with safety to itself withstand vehicles traveling at the speed otherwise permissible under this traffic code, the director of transportation services shall determine and declare the maximum speed of vehicles that such structure can withstand, and shall cause or permit suitable signs stating such maximum speed, to be erected and maintained at a distance of 100 feet before each end of such structure.
