Girders which supported the formwork system that was designed for lowering and sliding, as this elevated structure was approximately one half mile (0.80 km) long.
A Custom engineered and manufactured Formwork & Falsework System utilizing SCI's 6.5"; (165 mm) Aluminum Joists and Standard 7" (177.8 mm) Aluminum Strongbacks for this bridge rehabilitation project. The overhang system was used for the construction of the new concrete overhang and as a pedestrian walkway. Custom hangers, pedestrian protection, fencing, etc. also provided by SCI.

SCI's Bridge Deck Overhang Brackets, designed and used for the construction of the overhang concrete deck, and also as a work deck for the construction of the concrete parapet.
