Ferreira Construction is responsible for the staged demolition and replacement of bridge decks at four structures, demolition and full superstructure replacement at three additional structures, and the repair of structural steel at an eighth structure. Replacement decks at Structures 144.7 and 149.4 will be constructed using cast-in-place high early strength high performance concrete. Structures 143.2 and 151.1 will be re-decked with precast concrete panels with polymer grout connections. The decks and superstructures, including structural steel, at Structures 152.9A, 153.0S, and 153.1N will be replaced using prefabricated superstructure units during weekend high intensity construction cycles. Repair of the structural steel diaphragms will be performed at Structure 158.2. Incidental to the deck replacements, Ferreira will perform and oversee work including deck joint replacements, header repairs, asphalt resurfacing, latex modified concrete overlay, parapet replacement, substructure repairs, laminated elastomeric bearing replacement, temporary support of stringers, temporary traffic signal systems, installation of electrical conduits, new lighting standards, and maintenance and protection of traffic for multiple stages at each work location.
