The Heathcote Road bridge upgrade is a step closer with construction starting on the project at Engadine.

The new bridge will be located on the upstream side of the existing bridge and will provide one lane for westbound traffic while the existing bridge next to it will be modified to provide one lane for eastbound traffic.

This project will deliver lasting benefits for the community and the hard work to make this happen is starting now. When complete, the new and old bridge will deliver wider travel lanes and road shoulders while also ensuring the preservation of the historic original 1940s-era bridge and wildlife corridors. The current Heathcote Road bridge will also be upgraded with the road resurfaced, new railings installed and maintenance as required.

These upgrades complement previous safety improvements already carried out on Heathcote Road such as intersection upgrades, lane widening and the installation of lane markings which vibrate to alert motorists when they are outside their lane.

Minister for Metropolitan Roads Natalie Ward said this complex and important project will address safety concerns and improve traffic flow along this key route.

“Heathcote Road is a major road which links Liverpool and Heathcote, connecting Sydney’s southern suburbs to the motorway network in the south-west, so it is essential traffic flows smoothly and safely,” Mrs Ward said.

“The original plan was to widen the lanes of the existing bridge but we listened to the community and are building a new bridge to ensure the best outcome for the 22,000 vehicles that use Heathcote Road every day, including heavy vehicles.”

The new Heathcote Road bridge project requires several full road closures of Heathcote Road between New Illawarra Road and the Princes Highway. A detour will be in place during closures with local access maintained and the community will continue to be advised of exact times and dates. Work is expected to be completed by mid-2023.
