I walked over and watched the removal of the pedestrian bridge at Bow Trail and 24th Street SW this evening. Everything went off without a hitch.
First, the concrete bases holding the steel were removed from both sides. Next, the massive (300 tonnes ea.) mobile cranes came in on both sides and did their setup. When that was complete, the riggers prepared the bridge for the lift. The welders took over and cut the steel on both sides. At midnight, the bridge was lifted up and placed on the northside of Bow Tr. That process is documented here, by me:
