Architectus’ design concept for the Gold Coast Light Rail bridges is one
of reduction; to use as few structural elements as practicable, and to
design structures that are as slim as possible. This approach is employed to minimise the impact of the bridges on the environment; urban streetscape and landscape, and to optimise visual amenity.
Early analysis determined that bridge forms with a horizontal emphasis were most appropriate and of lowest impact on the landscape. The study of the geometry and form of piers, headstocks, and deck was dedicated to a search for the slimmest and most cost-effective structures. This approach has enhanced the visual integration between vertical and horizontal bridge elements, and has provided balanced and carefully detailed design solutions.
The outline of the parapet and deck of the Smith Street Overbridge extends visually from Parklands Drive over Smith Street, lifting over the undulating landscape and touching down adjacent to the Southeast bank of Loders Creek and the proposed GCRT Depot facilities.
The Nerang River LRV Bridge follows the existing highway bridge geometry, along the West side. The structure has been designed to achieve the optimum number of piers and hence have minimum impact on river afflux and navigation under and between the bridge structures.
