On 1 August 2007 at 6:05 pm, during rush hour traffic, the I35-W Highway Bridge in Minneapolis, Minnesota collapsed into the Mississippi River.

We’ll look at how a bridge could suddenly collapse after 40 years of service. And we’ll ask was there an issue with design, or was there abnormal bridge loading at the time of the failure? Or was there both?

A photograph of the loading on the bridge can be found in the NTSB failure report on page 26, see figure 16.

A show about engineering failures and disasters. We examine the technical, human and organisational causes of failure, and explore why our decision-making is not nearly as rational as we’d like to think.

Minneapolis Highway Bridge Collapse

As you can tell by the title of this episode this isn’t a normal episode of The Brady Heywood Podcast. In today’s episode we introduce you to a new show that we’ve been working on called Simplifying Complexity, a podcast all about complexity science.

Simplifying Complexity is all about understanding the underlying principles that govern how systems work; systems as diverse as economies, ecologies, cities and countries. In each episode, we'll meet with the experts, and learn everything from how economies can go boom or bust, to how the Medicis wielded power in Venice in the 1400s, and why large animals live longer than small animals. And above all, we'll learn about the principles that tie all of these things together. 

In the Brady Heywood Podcast, you learnt how things failed, from a technical standpoint, and an organisational standpoint. Simplifying Complexity takes us one step further, to understand how systems work, and just as importantly, how they fail. If you're interested, we've included a teaser of episode one of Simplifying Complexity, where we're joined by David Krakauer from the Santa Fe Institute, who's going to introduce us to the basics and the history of complexity science.

Introducing 'Simplifying Complexity'

In today's episode, we bring to a close our three-part series on the collapse of a pedestrian bridge in Miami, Florida, in 2018.

In part one, you heard about the cracks in the bridge and how nothing was done about them. And in part two, you heard about the serious errors that were made in the bridge's design.

In this episode, we take a deep dive into two unanswered questions from this failure: just why did everyone ignore the cracks in the bridge; and why did a rigorous checking process not identify the errors in the bridge's design?

Miami Bridge Failure - Part 3

Today's episode is the second of a three-part series on the 2018 collapse of the International University Pedestrian Bridge in Miami, Florida.

In our last episode, you heard how a pedestrian bridge under construction at the Florida International University collapsed in 2018 and killed six people. While many things came together to cause the collapse of this structure, the National Transportation Safety Board (NTSB) identified some serious errors in the design of the bridge.

In this episode, we take a deep dive into these serious design errors as we attempt to understand why this tragedy occurred.
