Construction traffic on the Oxley Highway

Oversize Over Mass Traffic

Heavy Vehicle Movements (other than OSOM)

Winterbourne Wind EIS has provided us with an insight into the construction period. Lets add Ruby Hills. Construction for Winterbourne is 30 months, Ruby Hills longer, with a peak period of 10 months for Winterbourne, presumably longer for Ruby Hills.

During peak construction, truck movements required for Winterbourne during peak period, is 288 semi-trailer loads or B-double loads per day. Note: current number of heavy vehicles on Oxley highway is 115/day.

For the remainder of the project, this number is 176 semi-trailer loads or B-double loads per day. During this construction period, operation will be 6 days a week, 7am till 6pm Monday to Friday and 8am to 6pm Saturdays.

The cost-benefit analysis should include the impact to our valuable landscape and biodiversity.

Imagine this …

The 950 cubic meters of concrete and the 150 tonnes of steel required for 1 footing. So multiply this number by 283 and we have coming into Walcha 42,450 tonnes of steel and 268,850 cubic meters of concrete that will be buried in our landscape. One's mind must boggle at the scale of how our landscape is being changed. This is just the footing, and does not include any construction of sub-stations, transmission towers, roads etc.

To put this in perspective the footings for 283 Wind turbines proposed in Winterbourne and Ruby Hills will require more than 41,000 concrete trucks alone.

Source and verification of information ...

The numbers we are providing for Winterbourne, have been sourced directly from Vestas EIS, or Project Director Doug Landfear in written correspondence.

With regard to numbers of OSOM movements per turbine, we have validated this number with the Golden Plains Wind farm project.

For the transport numbers for the proposed Ruby Hills projects, which will also be using the Oxley Highway as access route to site, we have made the assumption of the same number of vehicle movements per turbine as given for Winterbourne through their EIS. We have attempted to verify these assumptions with Walcha Energy. We have received a response from Walcha Energy’s Gold Coast based consultants who were not interested in clarification these numbers, and informed us to wait until the EIS and Traffic Impact Statement is completed. This could be years down the track.

We welcome scrutiny of these numbers. While the numbers are scary, they are not scaremongering. The reality is that these projects are unprecedented in size and place, and both of these projects have been initiated by a developer with intent to sell the project before approval. Ruby Hills has recently reported to Council their intention to sell, and Winterbourne Wind has been sold to Vestas, and then again to CIP (Copenhagen), pending project approval.
