At the Hanford Viaduct near Grangeville Boulevard, carpenters are working to erect falsework for the construction of the superstructure. More than 900 pre-cast concrete girders will be needed for the superstructure, all of which will be fabricated at the Dragados-Flatiron Joint Venture Pre-Cast Girder Facility just steps away from the structure. The first girders will be set for the superstructure later this summer.
