Section 32-5A-176

Special speed limitation over bridge or elevated structure; conclusive evidence of speed.

(a) No person shall drive a vehicle over any bridge or other elevated structure constituting a part of a highway at a speed which is greater than the maximum speed which can be maintained with safety to such bridge or structure, when such structure is signposted as provided in this section.

(b) The Department of Transportation and local authorities on highways under their respective jurisdictions may conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and if it shall thereupon find that such structure cannot with safety to itself withstand vehicles traveling at the speed otherwise permissible under this chapter, the Department of Transportation or local authority shall determine and declare the maximum speed of vehicles which such structure can safely withstand, and shall cause or permit suitable signs stating such maximum speed to be erected and maintained before each end of such structure.

(c) Upon the trial of any person charged with a violation of this section, proof of the determination of the maximum speed by the Department of Transportation and the existence of the signs shall constitute conclusive evidence of the maximum speed which can be maintained with safety to such bridge or structure.
