Medium term (5-10 years)
Bridgewater, Tas


The Bridgewater Bridge, which is part of the National Land Transport Network, does not meet contemporary loading and design standards. The bridge provides a single lane in each direction, and has a posted speed limit of 60 km/h.

The existing bridge and causeway are near the end of their serviceable lives. The bridge has high maintenance costs due to its age, and future refurbishments will be increasingly costly and limited in effect.

Proposed initiative

The initiative involves the development of an alternative Derwent River crossing.

The Tasmanian Government finalised a business case for the preferred option and submitted it to Infrastructure Australia in November 2018.

Next steps
