5 PROJECT POTENTIAL TRAFFIC IMPACTS
The majority of the project works are to be undertaken within existing
electricity transmission line easements. Minor realignments have been
designed to minimise environmental impacts, rationalise line infrastructure
and provide more secure and reliable energy supply network for the North
Coast. The location of all interactions between the line and road network over
the project area is listed in Table 5.2 and shown in Figure 5.1to 5.6. The
potential impact of the project works on the road network is then examined in
terms of the construction activity that is to be undertaken.
5.1 CONSTRUCTION PHASE
The EA (ERM 2009) identified potential environmental impacts associated
with the construction activities for the Project. These are summarised in Table
5.1 below.

• Temporary, short term traffic delays;
• Full/partial closure of roadways;
• Traffic detours may be used in some locations to re-route
traffic;
• Safety of road users and construction staff; and
• Disruption to normal traffic movements for residents adjacent
to project works.
