• Abstract:
  In the fall of 1980, an experimental ice detection system was installed on the Fremont Bridge in Portland, Oregon. this bridge, which caries I-405 over the Willamette River, has a history of icing problem when the deck is wet and the temperature hovers near freezing. The upper deck of the main span is especially vulnerable because of its height and thin deck section. The ice detection system allows bridge surface conditions and temperatures to be monitored constantly from a remote location, and assists maintenance workers in their response to the deicing needs of the bridge. ; The experimental feature of this project was to evaluate, under actual field conditions, the mechanical and electrical reliability of an ice detection system and the validity of its output in Oregon.
