A truss and gusset plate remnant (U10-U11W truss) recovered after the I-35 W Mississippi River Bridge collapse on August 1, 2007. This remnant is from the U10 and U11 truss nodes which were identified by the National Transportation Safety Board (NTSB) as a likely initiation site for the bridge failure.

I-35W Bridge Collapse

The I-35W (Interstate 35 West) bridge over the Mississippi River in Minneapolis opened to traffic in 1967. Thousands of vehicles drove across it every day, but no one imagined that a mistake in the bridge’s design, made over forty years prior, would have such disastrous consequences on one summer evening in August of 2007.
