Up to 48,000 vehicles, 700 cyclists and 750 pedestrians cross Halifax’s Macdonald Bridge every day.  In March 2015, Halifax Harbour Bridges (HHB) began an 18-month, $150-million project to re-deck the suspended spans of the Macdonald Bridge. This significant technical achievement has been dubbed The Big Lift, and is only the second time in history the suspended spans of a bridge have been replaced at night and in use during the day. The Social Sciences and Humanities Research Council (SSHRC) has provided support to this team of scholars to study different community aspects of the project.  The panel will report some of its findings to date.
