Heathcote Road Overtaking Lane

Transport for NSW is proposing to upgrade Heathcote Road at Engadine. The proposal will extend the existing westbound overtaking lane beyond the new Heathcote Road Bridge, this will allow traffic to safely overtake slower vehicles on the ascent to improve traffic flows and reduce delays. 

The project is part of a $180 million Government commitment to improve safety and efficiency on Heathcote Road and build on the gains won with the duplication of the new Heathcote Road Bridge.

Transport is undertaking investigations to understand the landscape at the location of the new overtaking lane. You may see us out and about in the next few months as we conduct these site investigations.

We plan to consult the community in late 2025 on early design for the overtaking lane.

Heathcote Road is a major arterial road that runs between Liverpool and Heathcote, connecting Sydney’s southern suburbs to the motorway network in the south-west including the M5 and M7 motorways. It is also a key link for commuters who drive, walk or cycle to Holsworthy Train Station and the Holsworthy Army Barracks.

Heathcote road is around 24km long and connects Newbridge Road at Liverpool with the Princes Highway at Heathcote. 

Transport for NSW is delivering many improvements along the Heathcote Road corridor.

Included in this investment is widening the road between Holsworthy and Voyager Point, planning for duplicating Heathcote Road between Voyager Point and Engadine, and the already completed Heathcote Road Bridge widening at Woronora River.
