The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included a number of unique features that had to be addressed by the Contractor during construction, including a unique pylon saddle design for such a light steel structure, and the use of epoxy coated strand for stay cables with grit used for friction during erection. This paper discusses the process of construction, and addresses some of the challenges brought about by the character of the design.
