One of the key elements that caused the Interstate 35W Bridge to collapse is now on display in Minneapolis.

NTSB said the gusset plates at the U10 nodes failed under a combination of substantial increases in the weight of the bridge, which resulted from previous modifications, and the traffic and ...

WASHINGTON, D.C. — The Interstate 35W bridge collapsed when a too-thin gusset plate ripped along a line of rivets, initiating a collapse that killed 13 people and injured 145. That conclusion ...

National Transportation Safety Board investigators probing the Aug. 1 collapse of an Interstate highway bridge in Minneapolis have found that some of the gusset plates in the bridge's main trusses ...

After the I-35W collapse in Minneapolis, the NTSB found 16 of those plates fractured – something not to be expected because gusset plates are normally the strongest part of a bridge, Rosenker said.

Investigators have found 16 fractured gusset plates from the center section of the steel-deck truss bridge, Rosenker said Tuesday at a news conference.

A buckled steel plate may be all it takes to bring down a 40-year-old structure like the Minneapolis I-35W bridge, which collapsed suddenly on Aug. 1 and killed 13 people. Forensic engineers ...

The board found that the designers of the doomed bridge failed to perform some necessary calculations on the critical steel beam gusset plates that eventually gave way.

But the investigation uncovered that the gusset plates did not meet engineering guidelines for 1967, the year the bridge was completed.

Gusset plates have since become the focus of special inspections at 25 Minnesota bridges that bear engineering similarities to the I-35W bridge, including the Interstate span, which was closed ...

A gusset plate from the bridge will be on display at the Mill City Museum July 28 to Aug. 30. "What we have behind me is a piece of that history, probably the most significant piece of that history.

The $500,000 re-evaluation follows Tuesday's preliminary report blaming gusset plates that connect bridge beams for the Interstate 35W bridge collapse.
