7.3        Proposed Site Access Arrangements & Adequacy
The proposed access arrangements generally comply with Austroads and Council Requirements.
However, it is recommended that adequate site access widths are provided to allow for an
incoming vehicle to pass two vehicles waiting to exit and that their approaches are sealed for at
least 20m prior to entering Lake MacDonald Drive.
The sight distance requirements at the White Pit Quarry access have been reviewed, with the
northbound visibility hindered due to the existing vertical road alignment of Lake MacDonald
Drive. Adequate sight distance can be achieved for truck activity based on a speed reduction to
60km/h. However, TTM have road safety concerns in relation to drivers observing this speed limit
and the level of slow turning truck activity.
It is therefore recommended that this site access is used for a short period in order to establish
the site and enable for a secondary site access to be internally constructed and located
approximately 100m to the north. The location of this secondary access will provide adequate
sight distance in both the north and south directions, as shown in Figure 7.3.
