Heathcote Road Upgrade

Project Overview

The Heathcote Road upgrade is an important project that will help reduce congestion, improve road safety, and provide more reliable journeys for all road users.

Heathcote is a major arterial road connecting Sydney’s southern suburbs to the motorway network in the south-west. It is also a key link for commuters who drive, walk or cycle to Holsworthy Train Station and the Holsworthy Army Barracks.

The NSW Government engaged Ertech to upgrade the 2.2-kilometre section of Heathcote Road between Infantry Parade, Holsworthy and The Avenue, Voyager Point.

The project includes five road bridges including one Super T bridge over an electrified rail and the demolition and replacement of two existing creek bridges. There is also a steel utility bridge over a creek.
