This curved pedestrian bridge over the Reedy River in Greenville, South Carolina, is supported by a single suspension cable at the outer edge of the bridge. Two inclined and tapered tubular steel masts, each 200’ (approx. 61 m) apart and stabilized with single sloped back stays, support the main cable. A circumferential steel truss below the outer edge of the 7” (approx. 18 cm) deep concrete deck provides the necessary stiffness. The torsion in the deck created by the one-sided support is balanced by a series of pre-stressed ring cables below the deck. The resulting axial compression in the deck combines with the axial tension in the ring cables to balance the deck torsion. With no visible means of support to the inner side of the deck, the bridge appears to float over the landscape.
