How Vulnerable Is Alaska’s Transportation to Climate Change? Managing an Infrastructure Built on Permafrost

A featured article in the January-February 2013 issue of the TR News 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.

The TR News is TRB’s bimonthly magazine featuring timely articles on innovative and state-of-the-art research and practice in all modes of transportation. It also includes brief news items of interest to the transportation community, research pays off articles profiles of transportation professionals, workshop and conference announcements, new book notices, and news of TRB activities. Submissions of manuscripts for possible publication are accepted at any time.
