Impacts of Climate Change on Alaska’s Transportation

A recent feature article in TR News, the magazine of NRC’s Transportation Research Board, explores how climate change in Alaska is forcing engineers and planners to adapt both to warming and to cooling trends.  With warming permafrost, coastal erosion, and increasingly dramatic storms and flood events, Alaska’s highways, runways, and other infrastructure are frequently icing, cracking, and washing away. Although these adversities challenge all of the state’s major transportation systems—maritime, aviation, and surface—the most acute and costly damage occurs within the road system.
