| Summary: | Tilt at two piers of the Confederation Bridge was measured from January to April 2000. Additionally, ice drift, current and ice thickness were measured in a collaborative effort with the Bedford Institute of Oceanography. Time- lapse video records of ice conditions were obtained from a traffic observation camera on bridge. The response of the piers to wind loads was used as a first order means to determine foundation stiffness and convert tilt to ice force. Typical tilttime records for a two-day period in March are presented. A maximum ice load of 0.9 MN was obtained during a period when ice rid ges with keels up to 4 m deep were measured.
