A c a s t - i n - p l a c e c o n c r e t e b r i d g e provided the aesthetic solution when Sachs Properties Inc., owners of the C h e s t e r f i e l d R i d g e C e n t e r o ff i c e development complex in Chesterfield, Mo., needed a bridge for access to their new parking structure and six-story building. The complex site geometrics called for a bridge to span Swingley Ridge Road, while also providing access to the rooftop level of a new parking structure. A new, 322-ft-long bridge spanning Swingley Ridge Road was desired to allow easy access to Chesterfield Ridge Center from the nearby North Outer 40 parallel connector road and I-64. A 100-ft-long upper level drive extension, projecting from the bridge, was also needed for access to a new parking structure. A cast-in-place, reinforced concrete bridge, T-shaped in plan view, provided the elegant solution desired. The monolithic concrete structure, profile sWinGley ridGe road BridGe / ChEStERfIEld, MO.
