Sec. 489(7). Special speed limitations on bridges.
It shall be unlawful to drive any vehicle upon any public
bridge, causeway or viaduct at a speed which is greater than the
maximum speed which can with safety to such structure be
maintained thereon, when such structure is sign-posted as provided
in this subsection.
The City Manager upon request, or upon his own initiative
may, conduct an investigation of any public bridge, causeway or
viaduct, and he shall determine and declare the maximum speed
of vehicles which such structure can withstand, and shall cause
or permit suitable signs stating such maximum speed to be erected
and maintained at a distance of one-hundred feet beyond each
end of such structure. The findings and determination of the
City Manager shall be conclusive evidence of the maximum speed
which can with safety to any such structure be maintained
thereon.
