Inside Infrastructure Podcast

In this episode of Inside Infrastructure, Marnell Gibson, P.E., joins our hosts James Nagelvoort, P.E., and Ben Valdez to unpack a question everyone asks but few understand: why do bridges cost so much and why do they take so long to build? Marnell reflects on her path to becoming a professional engineer and the major bridge projects she’s helped lead. She also shares an insider’s perspective on the hidden challenges, unexpected rewards, and lasting appeal of public works and project management. Inside Infrastructure is a podcast where public works professionals come together to explore the often-overlooked systems that shape our everyday lives. From hometown projects and statewide freeways to careers in public works and the politics behind infrastructure, each episode offers a clearer view of the world built around you—through thoughtful conversations with the people who build it.

As a lifelong public servant who has served as San Diego City Council President, Interim Mayor, Assemblymember, and now Mayor, he brings a valuable perspective on the challenges and opportunities shaping San Diego today.
