In 2017, this project in Austin, TX bridged a ravine to connect subdivisions in a residential area. The project featured a 55-ft wide and 36-ft high roadway embankment constructed with Reinforced Earth® MSE walls and precast concrete half-connector coping to accommodate the parapet. A TechSpan® concrete arch was included in the design to allow for drainage through the ravine, to the nearby Colorado River. The arch was composed of 21 full-width units and 2 half units, standing 15-ft tall with a 39-ft span and a thickness of 10 inches. The cast-in-place footings were founded on limestone, ensuring stability and durability for the bridge. The infrastructure enhancement helped to improve the connectivity in the area.
