Segment placement at Span 14, located between Pier 13 and the east abutment on the Wisc. bluff. Segments are placed at this location by a ringer crane. The ringer crane lifts the segments from the barge, to the bluff, onto a rail cart that moves it into place. Once in place, crews use jacks to make sure the segment is lined up correctly. Segments are staged with a small gap between them and epoxy is applied to each segment. Segments are then post-tensioned together with PT bars prior to the epoxy hardening. Photo from July 5, 2016.
