IBTTA appoints Kathryn Clay as new executive director and CEO

The International Bridge, Tunnel and Turnpike Association (IBTTA) has appointed Kathryn Clay as its new executive director and CEO, effective January 6, 2025. Clay succeeds Patrick Jones who led the IBTTA for 23 years.

Clay was most recently the president and CEO of the International Liquid Terminals Association, where she drove record revenue growth, spearheaded industry-first advocacy initiatives, and supported innovation, safety, and environmental compliance. Her impact earned her recognition as one of the “100 Top Influencers” in the global terminals industry by Storage Terminals.

“We are excited to welcome Kathryn Clay as IBTTA’s new leader,” says James Hofmann, CEO and executive director of the North Texas Tollway Authority and 2025 IBTTA president. “Her multidisciplinary expertise in science, energy, technology, and public policy aligns perfectly with IBTTA’s mission to advance innovative and sustainable transportation systems. With Kathryn’s leadership, we are ready to address the critical infrastructure funding gaps facing our communities. Tolling and user-fee financing are essential tools for building and maintaining sustainable transportation systems, and Kathryn’s vision and expertise will help position IBTTA to drive innovative solutions for these pressing challenges.”

Clay’s career spans high-level roles in energy, technology, and public policy, including work on Capitol Hill, where she helped shape key legislation like the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007.

Earlier in her career, Dr. Clay held key positions at the American Gas Association and the Alliance of Automobile Manufacturers, where she developed strategies on advanced vehicle technologies, energy efficiency, and environmental policy. She also served as a staff member for the U.S. Senate Energy and Natural Resources Committee, contributing to major legislation, including the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007.

With a Ph.D. in applied physics from the University of Michigan, Dr. Clay brings a data-driven approach to her work. She has published research on advanced battery technologies and served as an adjunct professor of physics at Georgetown University. Additionally, she holds certifications from the American Society of Association Executives and the National Association of Corporate Directors.

“I am honored to join IBTTA at this pivotal moment for transportation and infrastructure,” adds Clay. “Patrick Jones has left an extraordinary legacy of collaboration and leadership, and I look forward to building on that foundation. As infrastructure funding gaps grow, tolling and user-fee financing are more critical than ever to ensuring safe and sustainable transportation systems. Together with IBTTA’s members, we will advance innovative solutions that connect communities, support economic growth, and address the challenges of the future.”
