          Project delay
          Western Power had planned to undertake these works between August and
          December 2007. However, due to the power requirements in the Perth CBD during
          this time and other ongoing works in WA, Western Power was unable to carry out
          the work as scheduled. This project has subsequently been rescheduled and
          works will now take place from January to June 2008.

          Burying the cables
          This major project will begin with the excavation of a trench approximately 1.2 metres
          deep down the centre of Milligan Street. This trench will be barricaded to ensure
          public safety. Once the cables are laid and buried, the trench will be backfilled and
          the road surface restored to its original condition.
          Before commencing, preparatory work is required on certain sections of Milligan
          Street at the Murray Street and Hay Street intersections. This preparatory work will
          take place over several weekends to minimise disruption to weekday traffic and
          eliminate the need for entire intersections to be affected at any one time.

          Traffic interruptions
          Western Power will endeavour to minimise traffic disruptions by working outside
          of peak traffic times and on weekends where possible.
          Traffic interruptions are expected along Milligan Street, Hay Street and Murray
          Street as a result of the excavation of the trench and cable installation.
          Western Power is working with the City of Perth and Main Roads WA to safely
          manage the traffic flow.
          Street parking in certain sections of Milligan Street may be restricted during the
          work and some pedestrian crossings may be temporarily closed. Western Power
          encouraged s motorists and pedestrians to us an alternative route through the
          CBD during this period.
          Western Power and its contractors will contact local businesses and landowners
          with up to date information about the proposed traffic diversions and lane closures.
          Information signs on Milligan Street will also notify motorists of any expected delays.
