Sarens has transported and installed a 1425 tonne steel bridge arch over James Ruse Drive in Rosehill, Sydney, as part of the ongoing construction of the Parramatta Light Rail project.
The bridge is the second largest in New South Wales and was mobilised for its transport from the fabrication site before being lifted and lowered onto steel arch bearings.
When in full service, it will be used as a light rail overpass as well as provide walkways for pedestrians and bikes.
As part of the installation, Parramatta contracted Sarens, to carry out the lifts. The steel materials for the bridge were provided by S&L steel.
Sarens Project Manager Minhaj Rizvi said a small crew of six workers were able to successfully complete this bridge installation in record time.

- New bridge for Rookwood Weir complete
- Hurstbridge Line Duplication contract awarded
“It was a challenge to work within strict constraints to get all the pieces mobilised, assembled, and installed, but our design experience allowed our engineering team to avoid any delays and be extremely efficient,” Rizvi said.
The light rail, which is expected to be fully operating in 2023, will link several important destinations between Westmead and Carlingford.
In total, all materials for the bridge weighed 1425 tonnes and were 64 metres long. Sarens’ cranes lifted the bridge to a height of 11.7 metres. Towers, bracings, modular lifting beams, and strand jacks came from Belgium, and the on-site team required four weeks to set-up and functional test all the equipment before the installation could be safely completed.
