VIC level crossing removal: piling progress and bridge foundations for engineers
Reviewed by Tom Sullivan
First reported on Roads & Infrastructure (AU)
30 Second Briefing
Piling is complete for a new road bridge over the Werribee train line in Altona, Victoria, as part of works to remove the Maidstone Street level crossing. A 140-tonne piling rig has drilled 23 bored piles up to nine metres deep and 1.5 metres in diameter, which have each been filled with reinforced concrete to form the bridge foundations. The works set the geotechnical baseline for the superstructure, with deep foundations designed to control settlement and maintain track and road alignment under traffic loads.
Technical Brief
- Bridge works occur directly over the operational Werribee rail corridor at Maidstone Street, Altona.
- Construction is part of Victoria’s Level Crossing Removal Project, targeting elimination of a defined high‑risk crossing.
- Rail safety controls require staged works and possession planning to maintain train operations beneath the bridge.
- Temporary traffic management around Maidstone Street constrains plant access, crane positioning and spoil haulage routes.
- Works are being delivered under state government oversight, triggering compliance with Victorian rail safety legislation.
- Removal of the level crossing is intended to reduce train–vehicle conflict risk and near‑miss frequency.
- Design must maintain adequate clearance envelope above the Werribee line for rollingstock and electrification upgrades.
- Similar Victorian removals have standardised bridge‑over‑rail solutions, simplifying constructability, approvals and safety assurance.
Our Take
Using a 140‑tonne piling rig to drill 23 large‑diameter (1.5 m) holes signals substantial ground improvement or deep foundation demand, which practitioners in Altona should read as an indicator of challenging subsurface conditions or significant load paths at this crossing.
Within our 681 Infrastructure stories, Victorian level crossing removals frequently appear in the Safety-tagged subset, underlining that these works are being framed as rail–road interface risk reduction projects as much as congestion or capacity upgrades.
The scale of piling on this Altona job is comparable to heavy rail or bridge works elsewhere in Australia, suggesting that temporary works, spoil handling and vibration management will be non-trivial issues for contractors operating in a suburban environment.
