Cherry will describe recent efforts to capture and quantify open water and ice interactions with bridges from airborne photogrammetry throughout the course of the cold season. Groundwater, including aufeis, ice floes, sediment, and debris can all cause problems for bridge structures. This work is supported by the Alaska Department of Transportation and Public Facilities.
