In this episode, we talk with Roberto Leon, P.E., Ph.D., professor of Civil and Environmental Engineering at Virginia Tech, about the aftermath of the Baltimore Bridge collapse, including what the future holds for its reconstruction and the broader implications for infrastructure resilience.

Engineering Quotes:
Here Are Some of the Questions We Ask Roberto:
- Can you provide an overview of the Baltimore Bridge collapse, including its immediate impact on both infrastructure and the community?
- What are the full financial repercussions, both immediate and long-term, of a port shutdown caused by traffic congestion?
- Was the Baltimore Bridge collapse due to a design flaw or just a terrible accident?
- Can stronger bridge designs, exceeding recommended standards, prevent collisions even if they’re not always implemented?
- Considering the bridge’s code design standards, how old is the bridge and was it built to meet those standards?
- Did older bridge codes, like the one for the Baltimore Bridge, have a lower chance of withstanding a ship collision compared to today’s standards?
- How do engineers balance the need for safety in structures like bridges with the cost of building them to withstand extremely rare events?
- Will the Baltimore Bridge collapse force the industry to rethink bridge designs for better collision protection?
- Why do we need engineers to explain the importance of safety features in bridges, since we naturally expect them to be safe anyway?
- Do cable-stayed bridges offer advantages in design flexibility or visual appeal that make them preferable for this replacement project?
- Given the need for a fast replacement, can building this bridge on an accelerated timeline be done safely and efficiently?
- With a fast-tracked timeline and potential hidden costs in the foundation, how can planners ensure this multi-billion-dollar bridge project stays on budget?
- If public awareness of bridge vulnerabilities led to increased funding, what additional protective measures could be implemented?
- With a four-year closure disrupting the community, how does this bridge rebuild timeline compare to similar past collapses?
- How will the community cope with the four-year bridge closure, affecting commutes, work access, and daily needs?
- How can engineers bridge the gap between technical expertise and public understanding?
- What advice would you give young engineers?
