Community angst over the WestConnex motorway will soon spread when plans for new motorway interchanges are unveiled for Rozelle and at Sydney University, Camperdown.

The interchanges will almost inevitably involve property acquisition and, in Rozelle and adjacent Lilyfield in particular, will require the construction of elevated ramps to Anzac Bridge and Victoria Road.

More detailed plans for the motorway interchanges are set to be unveiled by NSW Planning and Environment in the next few weeks, after the organisation building the $16.8 billion toll road – the Sydney Motorway Corporation – lodged planning documents last month.

Yet the interchanges are already raising the ire of local politicians opposed to the motorway, after previous motorway entrances at St Peters and Haberfield and Concord were criticised for their impact on densely populated neighbourhoods and local roads.
