“CAUTION: TEST TRAMS IN OPERATION

As major works for the City Tram Extension Project are nearing completion,
tram testing will occur on the line tonight (Sunday 3 June) from
approximately 12.30am.

The testing of the line will be conducted on the network, including the new
sections of track along North Terrace to East Terrace and on King William
Road to the Festival Plaza Precinct.

Testing will take place in the early hours of the morning to avoid any
disruption to services.

Motorists and pedestrians are reminded to exercise caution while the
testing is carried out.
