The construction of Taney Bridge, Ireland

LUAS Line B consists of a new light rail system from Sandyford to central Dublin. Through Dundrum the line crosses a busy road junction. The client and their design consultants chose a cable-stayed structural form with a single asymmetric tower for this bridge. An alternative segmental deck design was carried out by Benaim for the contractor Graham Construction that would utilise previous experience with segmental construction. This paper outlines the construction philosophy and the development of the alternative design. The deck form, which is a precast concrete shell composite with an in-situ concrete infill, is unusual. The advantages of this form over the more conventional all in-situ or all precast type are discussed.
