Road works to divert the road and allow for the Elizabeth Quay development were scheduled for late 2013.
But Metropolitan Redevelopment Authority (MRA) chief executive Kieran Kinsella said these works had been delayed until after Australia Day.
‘Traffic management will be put in place to close Riverside Drive for the annual Skyworks event, and the section from Barrack Street to William Street will not reopen following the event,’ he said.
‘Diverting the road in January means the change in traffic flow will occur during the summer school holiday period when there are fewer cars on the road.’
The works will set Riverside Drive further back from the edge of the Swan River, between William and Barrack Street.
These changes are expected to allow five sites to become available for development between Riverside Drive and The Esplanade. The road works will also create a new eastbound connection from Point Lewis Rotary onto Mounts Bay Road and William Street. This section of the road is currently only open to westbound traffic.
Mr Kinsella said ongoing works on The Esplanade, Barrack Street, Mounts Bay Road and William Street had caused the delay to work on the Riverside Drive diversion. But he said the Elizabeth Quay project was ‘on time and budget.’
‘There will be no delays to the project as a result of reprogramming the diversion of Riverside Drive,’ he said.
