A key commuter link is about to get a big boost with a new bridge over the Woronora River coming as part of the Heathcote Road upgrade at Engadine.

Member for Heathcote Lee Evans said Transport for NSW will partner with Fulton Hogan to deliver this complex and important project, which is designed to address safety concerns and improve traffic flow.

“Heathcote Road is a major road which links Liverpool and Heathcote, connecting Sydney’s southern suburbs to the motorway network in the south-west including the M5 and M7 motorways,” Mr Evans said.

“The original plan was to widen the lanes of the existing Heathcote Road bridge over the Woronora river but I am thrilled to announce we are building a new bridge.

“This 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 will be modified to provide one lane for eastbound traffic.

“The changed design improves safety by providing wider travel lanes, road shoulders and a central concrete median barrier while also ensuring the preservation of the historic original 1940s-era bridge and wildlife corridors.

“This upgrade will improve safety for the 22,000 vehicles that use Heathcote Road every day, including heavy vehicles.”

Member for Holsworthy Melanie Gibbons said the upgrade will complement a number of safety improvements carried out on Heathcote Road.

“Transport for NSW has already reduced the speed limit, carried out intersection and lane widening improvements in various locations, and installed audio tactile lane markings along the entire corridor which vibrate to alert motorists when they are outside their lane,” Ms Gibbons said.

“These improvements have been instrumental in boosting safety along the corridor and form part of the long term vision for Heathcote Road.”

Road users can expect to see investigation and surveying work starting in the coming months, and work on the new bridge is on track to start in the second quarter of 2022.
