On the east side of the Wasco Viaduct, ironworkers and carpenters are working on the steel beams and forms for the edge girder of the pergola section. The edge girders will support the precast girders that are expected to be set during the summer. Crews will set more than 70 girders from east to west on the pergola section over the BNSF railroad.
At the northern portion of the viaduct, crews are erecting the falsework that will support the box girders, linking the abutment with the pergola section just to the south.
