Design and construction of a 347m incrementally launched concrete bridge along the Princess Highway West of Gerringong and spanning over the existing South Coast railway crossing. This bridge was always identified as a key area of risks for the project and the launch bridge solution provided many benefits: - Reduction of environmental impact of the adjacent protected wetlands. - No need for road closure nor rail closure. - Elimination of many high-risk work activities. - More aesthetic pleasing structure: longer spans, slender structure. - Significant reduction of maintenance requirements.
