I-35W Bridge
Failure
-
The National
Transportation Safety Board (NTSB) announced that a serious design flaw
was found in some of the gusset plates on the I-35W bridge in Minneapolis,
which collapsed on August 1, 2007. As a result, the NTSB issued a
recommendation that the Federal Highway Administration (FHWA) require
bridge owners to verify that the stress levels in all structural elements,
including gusset plates, remain within applicable requirements whenever
planned modifications or operational changes may significantly increase
stresses. This would apply to all non-load-path-redundant steel truss
bridges within the National Bridge Inventory.

The collapse of this bridge led to 13
deaths, 145 injuries and serious disruption to the lives of thousands of
motorists and residents in the region. ASCE again extends it condolences
to the victims of this tragedy. As a profession, it is our obligation to
learn all that we can from such events. ASCE will continue to monitor the
NTSB’s investigation and will incorporate the recommendations and lessons
learned into our future technical and professional policies and standards.
- ASCE urges its members to review the NTSB’s
report and recommendations.
