The Ison Road Project involves the construction of an Overpass and Extension in Werribee to provide a vital new link to the Princes Freeway.
Decmil has delivered the Ison Road Overpass, a new four-lane dual carriageway with a dual span overpass crossing over the Geelong-Melbourne Rail line. The Ison Road Extension, currently under construction, will connect with the Ison Road Overpass to form the new link to the freeway between Melbourne and Geelong.
This is the third project Decmil has been awarded as part of MRPV’s new Program Delivery Approach, which has a strong focus on collaborative, panel-based procurement during the tender phase leading to the delivery works.
Ison Road Overpass
The scope of work for this project involved the design and construction of a new four lane dual carriageway between Bulban Road (East) and Browns Road with a dual span overpass crossing over the Geelong-Melbourne Rail line.
The scope of works completed by Decmil included:
- Bridge deck and embankments allowing for a future ultimate 6 traffic lanes
- New shared user paths along the alignment
- Dedicated cyclist path in front of the northern abutment
- Proving, relocation and protection of Utility Services
- New lighting, road signage and landscaping.
Fauna protection was key on this project. During establishment of the project, Decmil’s project team successfully identified and relocated several protected species including the Grassland Earless Dragon and the Legless Lizard.
Ison Road Extension (currently in construction)
This project comprises the design and construction of of a four-lane divided carriageway that will connect the Ison Road Overpass (north of Browns Road) to Wests Road / Geelong Road.
The scope of works includes a new 1.3km of a four-lane road between the Ison Road Overpass and Geelong Road (Princes Highway) interchange. Works also include:
- walking and cycling paths connecting the Ison Road Overpass to the Princes Highway (Geelong Road)
- major cross road drainage culverts
- proving, relocation and protection of Utility Services
- provision for bus stops and safety barriers along the alignment
- new street lighting, road signage, and landscaping.
