In March 2016, Infrastructure Tasmania published its review of a design and cost estimate for the construction of a replacement structure for the existing Bridgewater Bridge, which considered various options for a replacement structure and provided advice as to the most feasible crossing solution. As part of the 2018-19 federal budget, the Australian Government announced a $461 million grant towards the construction of a new Bridgewater Bridge, representing 80 per cent of the expected total construction cost. The Tasmanian Government is expected to contribute $115 million. Construction was expected to commence in 2019; however, following independent assessment of the project by Infrastructure Australia in July 2019, the evaluation identified a range of issues, which may add to costs and require further work to address, and recommended that the Tasmanian Government revise its business case. The project is scheduled to start design and approvals in 2019, with the design to be agreed by the end of 2020. Substantive construction is expected to commence in 2022 and completion is targeted in 2024. The concrete box girder bridge is expected to carry dual carriageways with a clearance of above the Derwent River.
