August 19, 2005: Grace Structure
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.
