A view of the main Grace span (March 6, 2005). The peaked superstructure above each concrete support pier acts as a cantilever. The central pinned structure has a lower peak.

The Grace spans consist of 3 major components: a center span where the pinned component is on the lower left and lower right.

and a pier supporting a cantilevered component (left) that is attached by a vertial element (Ken told me the name and I forgot) (right)

Removal of the Grace bridge will consist of dropping the central component into the Cooper River, leaving the cantilevered components for later removal.
