The Angus L. Macdonald Bridge has fully reopened after the completion of its “Big Lift” project in Nova Scotia, Canada. The endeavor involved replacing the entire suspended span and all the hangers of the 63-year-old suspension bridge and raising the bridge deck itself by nearly 10 ft to enable larger ships to pass beneath. Completely replacing the superstructure of this large suspension bridge segment by segment was an extremely complicated process; the bridge could only be closed at night and on weekends, and the installation of each new segment meant that the dynamic properties of the entire structure changed and all analyses had to be recalculated for each step.
