Hindmarsh Island Bridge

Construction of the Hindmarsh Island Bridge was completed using the incremental launch method of construction. The Hindmarsh Island Bridge consists of concrete deck cast onto steel girders that is supported by concrete piers and concrete abutments. The bridge spans 319m in which the profile of the bridge is curved horizontally. The navigational clearance is 14m high by 24m wide resulting in a compound vertical curve. The bridge beams were launched from each abutment to a position that allowed them to be fixed at two piers in the middle of the river.

Engineering Surveys was involved in all elements of the bridgeworks setting out including a complex arrangement of marine piles to support pier columns, accurate positioning and levelling of deck bearing headstocks, abutments, retaining walls, barriers and final pavement surface.
