Current work
Please allow extra time when travelling through the project area as you may experience some delays. You can view a list of all planned works within the project area in the current Roadworks Roundup.
The Roadworks Roundup is published every Friday afternoon and lists all our planned works for the next two weeks.

Changes at causeway roundabout in Granton
There will be changes to traffic movements at the causeway roundabout and a section of Lyell Highway in Granton from Tuesday, 15 April 2025 as part of the New Bridgewater Bridge Project. This work will include moving the causeway roundabout a few metres to the north, removing the existing traffic islands and upgrading a section of highway.

Motorists are asked to be aware of oversized truck movements from Bridgewater to both ends of the new Bridgewater Bridge via the Midland Highway, East Derwent Highway and Brooker Highway over the next six months as major construction continues.
More about Oversized movementsBrooker Highway over size vehicle detour
We are building a new northbound slow lane on the Brooker Highway as part of the New Bridgewater Bridge Project. To do this work, we need to reduce the width of the northbound lane of the Brooker Highway by relocating concrete barriers, which will restrict the movement of very large loads through the area. During this time, over-size over-mass (OSOM) vehicles with loads over 3.5 metres wide won’t be able to travel through the project site on the Brooker Highway and will need to follow a detour.

As part of the New Bridgewater Bridge Project, the northern end of Old Main Road has been closed. The closure is part of the final design and will facilitate other aspects of construction activities. Clear and appropriate signage has been placed in the area to ensure that non-local motorists are aware of the changes, and local residents are asked to plan their journeys and use alternative routes where possible. We understand that this may cause some inconvenience to residents and businesses in the area, and we apologise for any disruption that may occur. The project team will continue to provide regular updates on the progress of the New Bridgewater Bridge Project, including any further disruptions that may occur.

To take advantage of favourable conditions, and to minimise disruption to the wider community, the project is continuing with out of hours work (OOHW) in 2025. Standard construction hours are Monday to Friday from 7am to 6pm, and Saturdays from 8am to 6pm. Most high impact work including piling for the permanent bridge, will be carried out during the standard construction hours, with less impacting activities taking place outside of these times, as well as during standard construction hours.

To allow for the construction of the new Bridgewater Bridge, the Department of State Growth has closed the lifting span on the existing bridge. The lifting span will remain closed until the completion of the new Bridgewater Bridge in 2025. Vessels under 2.2 metres on an average tide are able to travel under the existing bridge without the lifting span being opened. The new Bridgewater Bridge will include a navigation clearance consistent with the Bowen Bridge, allowing vessels to move freely past Bridgewater towards New Norfolk.

To keep the public and our workers safe, the Bridgewater boat ramp and jetty will remain closed throughout the project. River users wishing to access the river can do so at the nearby Old Beach boat ramp, around 8 kilometres downstream. Nielsen Esplanade, including the playground, will remain accessible throughout the project. The project is planning to reinstate the boat ramp at the completion of the project, in consultation with Brighton Council.

Concrete barriers across the project site separate our workers from traffic and changes are happening in stages to minimise impacts.
In Bridgewater, traffic travelling south on the Midland Highway can access the new road under the northern end of the new bridge via the Gunn Street off-ramp.
Traffic then continues south over the existing bridge or north on Old Main Road.
There are pedestrian paths and safe access to the relocated southbound temporary bus stop near the northern end of the new bridge.
In Granton, the new section of the Lyell Highway is separated, with southbound traffic through Granton being moved onto a new single lane of the Lyell Highway.
This passes under the southern end of the new bridge onto the Brooker Highway towards Hobart.
Northbound traffic through Granton will stay on the new section of the Lyell Highway.
From Wednesday, 16 April, the new Black Snake Road bridge underpass will open to traffic, removing the temporary U turn on the Brooker Highway.
Traffic travelling south will use the new roundabout at the bottom of Black Snake Road and the underpass to access Black Snake Road while northbound traffic will continue to turn left into Black Snake Road from the Lyell Highway.
Traffic underneath the new Black Snake Road bridge will be one-way only, traveling west from the new roundabout and under the bridge to the Lyell Highway.
Traffic travelling from Black Snake Road into Hobart will continue to use the Granton causeway roundabout to turn and then travel south.
When travelling through the site, you will see workers and there will be traffic management in place. Please be patient and follow signs and any directions from traffic controllers.
The plans above show all of the different stages of traffic changes that will be implemented throughout the construction of the new bridge and interchanges. For more information on each stage click on the image to enlarge it and use the arrows to move between each slide.
