The $2.5-million Phyllis J. Tilley Memorial Pedestrian Bridge located in Fort Worth is the first steel-arch and stress-ribbon bridge in North America. Rebcon led construction on the Freese and Nichols-designed structure.
The post-tensioned steel stress ribbon, carrying prefabricated concrete deck panels, stretches from one end of the bridge to the other and rests on the rounded apex of the arch over the river. These two systems work in concert to create an efficient structure that appears to float over the landscape, with the tension in the stress ribbon balanced against the opposing thrust loading from the steel arch.
