Springvale road and rail grade separation

  • AU$142m project delivered in just over seven months.
  • One of Melbourne’s busiest level crossings, used by 50,000 cars, 218 trains and 5,000 pedestrians a day.

Tackling the busy Springvale Road level crossing was a key part of the Victoria State Government’s AU$38bn transport plan. The plan aims to deliver a safer and more reliable rail network.

Removing the level crossing required the relocation of Nunawading train station and the lowering of the railway line so it would pass under the highway. The road bridge deck was also reconstructed. 

Arup worked in close collaboration with partners to deliver this project within a tight timeframe and with minimal disruption to rail and road operations.

"The project has been delivered on time and on budget, and sets the benchmark for future projects."

– John Brumby, Victorian State Premier

4D modelling

To reduce construction time, Arup used 3D modelling with a high level of 4D schedule detailing. Modelling the construction sequence as well as the design allowed the team to show that a single whole-road closure would be better than a long period of lane closures.

A 10-day road closure was eventually chosen to replace 12 weeks of temporary lane closures. Rail shutdown was also reduced from 35 to 10 days.

Breaking the design of the station into individual elements improved safety and ease of installation, and prefabrication of components cut construction time even further. 80% of the station was prefabricated in this way, allowing construction to continue in parallel with infrastructure works.

Reduced congestion and improved safety

By successfully lowering the railway line under the road and relocating Nunawading station, the project has improved safety and reduced traffic congestion. Better facilities for bus and train commuters and safer pedestrian crossing conditions have also been achieved.
