Traffic Management Sub-Plan
Uncontrolled when Printed: Revision D
Date: May 2010
The installation of the transformers may require the total or partial closure of
roadways adjoining the substation access ways which will require suitably
qualified traffic controllers, and adherence to the traffic management
principles for stopping and/or merging traffic. The protocols for heavy
vehicle movements stated above are to be followed during the transport of the
transformers. The operation of installing the transformers may require the
total or partial closure of the roadways directly adjacent to the substations.
These roadways are listed below:
• Ewingsdale Road;
• Newrybar Swamp Road;
• Grays Lane; and
• Temple Street.
The rural location of the Ewingsdale Road, Newrybar Swamp Road and Grays
Lane will mean that only minor volumes of traffic are likely to be impacted by
the partial/total road closures. Temple Street is located in a built up area of
Ballina, however the connectivity of the road network provides numerous
detour opportunities. Detours are discussed in Table 6.1.
Following completion of construction activities, the substation would generate
very little traffic. Access to the facility would be at irregular intervals and
generally be light vehicle traffic during day time hours. Such traffic
movements would not have a significant impact on the level of service or
capacity of the local road systems.
5.5.2 Construction of New Substations
Two new substations are proposed to be built as part of the network upgrade.
The Suffolk Park substation is to be constructed at the end of Yagers Lane.
The substation will require upgrades to the existing road network leading to
the currently undeveloped substation site as described in Section 6.4. The
location of the proposed Brunswick Heads substation has yet to be confirmed.
Given their location, minimal traffic impacts are predicted for the construction
of the substations with only a minor increase in vehicle volumes and heavy
vehicle and construction plant for the relatively short timeframe required to
complete the construction of the substation.
