Ironworkers are hard at work at the Wasco Viaduct in Kern County. Crews are continuing to drill shafts where rebar will be placed to form columns for the pergola structure. On top of the deck, ironworkers with Pacific Steel Group are setting horizontal bars to link the stirrups of the girders for the west side of the pergola. When complete, the viaduct and pergola will be nearly 2,000-feet in length.
