WTI was well represented at the International Symposium on Systematic Approaches to Environmental Sustainability in Transportation last week, which was held at the University of Alaska Fairbanks. The symposium showcased recent development, practices, and advances to maximize environmental sustainability, and also provided a forum for professionals to discuss environmental challenges associated with design, construction, and maintenance of multimodal transportation systems under extreme conditions or in rural environments.  Laura Fay, Rebecca Gleason, Na Cui, Ning Xie, and Anbu Muthumani were all invited to lead technical workshops or present their research throughout the four-day program.  Participants also had the opportunity to tour unique research and infrastructure facilities in the area, including the Permafrost Tunnel Research Facility and the Trans-Alaska Pipeline System.
