Brian Road Intersection Upgrade - Appin Road improvements


Project overview

The Australian and NSW governments are funding projects to improve safety and support affordable housing in the Greater Macarthur Growth Area.

Project information


Appin Road is a key arterial road which connects road users travelling between south-western Sydney and the Illawarra. Locally the road services the suburbs of Appin, Gilead and Rosemeadow.

A safety review of Appin Road identified several opportunities to improve safety, such as by widening shoulder widths and improving the intersection at Brian Road. As such, Transport proposes to construct a roundabout at the Brian Road intersection as well as road widening and installing safety barriers along Appin Road.

A fauna underpass has also been proposed at the intersection to connect koalas near Ousedale Creek travelling between the Georges River Reserve and Nepean Corridors.

The koala underpass implements one of the key recommendations of the Cumberland Plain Conservation Plan and addresses a key issue identified in the Campbelltown Comprehensive Koala Plan of Management.


The Brian Road Intersection Upgrade would include a new roundabout and fauna underpass.

Key features include:

  • A new single lane roundabout at the intersection of Appin Road and Brian Road
  • A new 2.4m diameter and 36m long fauna underpass under Appin Road, with refuge poles at the fauna underpass entrances and an elevated timber log through the underpass to aid movement
  • A new vegetated fauna path to the new fauna underpass
  • Road shoulder and embankment widening, and new safety barriers and fauna fencing along Appin and Brian Roads
  • Fauna fence drop downs at either side of the underpass to allow trapped fauna inside the road reserve to escape
  • Utility relocations, drainage, pavement markings, street lighting and signage.
