Two CON/SPAN® structures were built using concave/ convex skewed units and curved wingwalls to match the inside and outside radius of the walkway’s horizontal curve. The curved alignment held not only to close horizontal tolerances, but also to vertical tolerances at four corners of the wingwalls. Precast footers were used, and the wall panels had a formliner face that provided an aesthetic appearance.
