Kyle Evans, the guy who made this YouTube of the bridge wrote this, " I still have time lapse of other days of the bridge move but here is the time lapse from the last day. The defining moment when the bridge finally reached the south side and was pulled into place. I had decided to set up my camera in a different location on other days but for the last day I chose a spot at the top of the abutment that I felt would show the most action.

In the video you can see at the beginning how they had to drop the north end of the bridge to bring up the south end high enough to get over the rollers. This portion of the operation was very delicate because they could not allow the central red tower to bear the entire weight of the bridge as it was not designed to do that so they had to move slowly and deliberately to make sure it didn't cause any issues."
