Dear sponsors, students, colleagues, and friends,

Welcome to the website of TriDurLE. I am glad that you’re here to find out more about what we do, and more importantly, how we can work together to maintain longer-lasting transportation infrastructure and to preserve a durable and resilient transportation system. TriDurLE was established in 2019 as one of the seven National UTCs funded by the University Transportation Center Program of U.S. Department of Transportation, and the only National Center focusing on “Improving the Durability and Extending the Life of Transportation Infrastructure.”

At TriDurLE, we believe that durability is a cornerstone of sustainability. The partnerships underlying this National UTC is based on the shared vision of “cost-effective innovations and holistic solutions to enhance multimodal infrastructure durability.” The Consortium universities represent diverse geographic and climatic regions, and are thus well positioned to explore cost-effective and whole-life-cycle solutions to infrastructure durability and life-extension.

TriDurLE will significantly impact multiple modes of surface transportation system and the quality of life of its users. Transportation infrastructure has a direct impact on the long-term economic growth in terms of GDP, employment, household income, and our global competitiveness. Yet much of our transportation infrastructure was built over fifty years ago and is in deteriorating conditions or simply overwhelmed by demand. Both the White House’s Legislative Outline for Rebuilding Infrastructure in America and the USDOT Strategic Plan for 2018-2020 identify and call for investment in rebuilding the Nation’s infrastructure to ensure safety, mobility and accessibility and to stimulate economic growth, productivity and competitiveness for American workers and businesses. The TriDurLE team has the expertise, skills, and collaborative background to take these challenges head on and provide effective solutions.

On behalf of all Center staff from our eleven Consortium universities, I welcome you to visit us or contact us for ways to collaborate in research, education, workforce development, or technology transfer opportunities. If you have an infrastructure durability challenge that we might be able to address or an idea for potential partnership, please call me at 509-335-7088 or email me.
