Allowing heavy semis
and other vehicles to drive over the top
was a different matter. As a temporary fix,
steel plates were secured
around the crack. But while the team continued
to investigate,
the bridge remained closed. This is the main navigation
span for the river, This is the main navigation
span for the river, and the fracture was found
about 80 foot from this pier on the northern side
of the bridge. The fracture had occurred
in one of the plates
on the side, one of the plates on the top
and part of the plate
on the bottom. More than half of the section
had been compromised
