Traffic Management Sub-Plan
Uncontrolled when Printed: Revision D
Date: May 2010
The most significant impact to traffic at both substation locations is the
importing of the transformers which requires the use of low loaders. This
may cause traffic delays during the delivery and may require partial to total
closure of the roadway adjacent to the substation during the installation of the
transformer. At the Suffolk Park substation site Yagers Lane may require
partial to total closure although minimal traffic volumes are expected to be
affected due to the rural location of the roadway.
The transmission line network will need to be connected to the substation
upon completion of construction. The transmission line connection activities
have the potential to cause partial or total closures of adjacent roadways while
the lines are being linked to the new infrastructure. Similar to the line
upgrades throughout the project, the connection will be completed in a short
period of time (less than one day) so road closures will be temporary.
5.5.3 Upgrade of Skinners Shoot Road and Yagers Lane
Skinners Shoot Road and Yagers Lane are to be upgraded to provide a suitable
trafficable surface to accommodate the heavy vehicle movements and oversize
loads associated with the transmission line upgrade and construction of the
Suffolk Park substation. Country Energy intends to upgrade the sections of
the road that are currently inadequate to allow construction traffic access.
Country Energy will repair to the pre-existing state any damage caused by
construction traffic.
Skinners Shoot Road is in poor condition and is considered substandard for
the current volume of daily traffic movements and the heavy vehicle
movements required to transport electricity transformers.
The first 1km of Skinners Shoot Road through the SEPP 14 Coastal Wetland
system will require some minor upgrade works. This will include pavement
improvements and widening of the sealed section from 3m to 4m with
bitumen surfacing within the existing wider unsealed road formation. Some
trimming of overhanging vegetation (branches only) will be required to
minimise potential damage from vehicle strike. As it does not involve any
clearing, levee construction, drainage or filling of the adjacent SEPP 14
Wetland, the Project does not trigger any of the referral and concurrence
provisions of SEPP 14. Appropriate mitigation measures have been
developed to ensure that the potential for any impacts upon the wetlands are
eliminated during construction.
