Current activities
It’s been a busy start to the year, with the start of major works to build the Ison Road Overpass.
The project team has made the most of our warmer months to build up the ground level to support the future 4 lane overpass.
Approximately 30 truck and trailers are coming in and out of the site around 80 times a day. They are bringing in 3,000 m3 of soil to compact and create the base for the road to be built on.
With the ground level rising about 8m since works began, the traffic lights on both Ison and Bulban roads have changed to allow trucks to enter and exit the site via this intersection.
Earthworks will continue over the coming months in preparation for the structural elements of the overpass to be built.
Our piling works also continue to create the foundation for the walls of the overpass to sit on. Eight bridge piles are completed, with a further 42 to be installed.
Next steps
Once the earth works and piling is complete on each side of the rail line, we’ll start construction of the bridge piers and retaining walls.
These piers support the weight of the bridge. The retaining walls stop the soil that we have built up to meet the overpass from moving.
The walls will be made of reinforced concrete and steel, and lifted into position on each side of the rail line.
We’ll also construct a central pier to provide an upright support to hold the centre of the beams, forming the bridge.
Change in traffic conditions
Traffic conditions at the intersection of Ison and Bulban roads have changed.
The temporary lane markers have been adjusted and the traffic lights are fully operational to allow trucks to access the project site through the intersection of Ison and Bulban roads.
Rumble strips have also been installed on Alfred Road to encourage vehicles to slow down as they approach the intersection of Alfred and Browns roads.
The 40km/h speed limit will remain in place around our work area while we build the overpass, to keep you and our workers safe.
This includes sections on:
- Bulban Road
- Galvin Road
- Browns Road
- Alfred Road.
With 3 different points of access for trucks and vehicles entering or exiting the site, it’s important to slow down and observe the traffic signs.
