Derwent Bridge, Tasmania is a locality on the Lyell Highway at the southern edge of the Cradle Mountain-Lake St Clair National Park.
It is just south of Lake St Clair and the Lake St Clair visitor centre; and it is north of Lake King William and the Butlers Gorge power station.
It is also the last inhabited location before Linda Valley in the West Coast Range – this section of the highway passes through the Wild Rivers National Park. In the past there were a couple of isolated houses along Lyell Highway that have been removed.
Today, Derwent Bridge features not only the bridge alluded to in its name – spanning the Derwent River – but accommodation units, and also a roadside public house.
