May 2016 Meeting-The 100 Year Bridge 

 

Speakers: Dan Springer and Amy Moore, LJB Inc

You have likely seen the ongoing media coverage about our nation’s crumbling infrastructure. But, what if bridges could last 100 years – long enough for your great, great grandchildren to use? This session covers the unique management and design challenges for the first ODOT project that utilizes long-lasting carbon fiber prestressing strands. For this pilot project, LJB designed the replacement of two existing multi-span prestressed concrete box beam bridges. One of the bridges will be constructed using conventional materials, while the other bridge will use carbon fiber (CFCC - Tokyo Rope) strands and stainless steel reinforcing in the superstructure. The bridge structures are similar enough to allow for comparison of the long-term sustainability of using different types of material. The presenters—including the project manager and lead bridge designer—will review the materials, challenges and long-term impacts of this unique bridge project that could have long-lasting effects on the future of bridge design.
