New Bridgewater Bridge - Infrastructure Pipeline (original) (raw)
A new Bridgewater Bridge will be constructed downstream of the existing bridge, providing a new connection between the Brooker and Midland Highways to the north of Hobart.
The scope of the project includes:
- a new, four-lane bridge with two lanes in each direction
- a speed limit of at least 80 km/h
- a shared path for cyclists and pedestrians
- safety screens and barriers
- a grade separated interchange connecting the Brooker and Lyell Highways in Granton, and
- connections to local roads in Bridgewater and Granton.
The navigation clearance of the new bridge will match the Bowen Bridge further downstream. However, the existing Bridgewater Bridge, with its vertical lift mechanism, will be retained, limiting the passage of larger boats up the Derwent River.
