Hunter 8 Alliance

Project Overview

The Hunter 8 Alliance was tasked with the triplication of the main North Rail Line between Singleton and Maitland with the aim of increasing the capacity of the Hunter Valley Rail Freight Corridor. Prior to the commencement of work, exports of coal from the Hunter Valley coal fields amounted to almost 90 million tonnes per annum. Due to the increased capacity of the rail line, this volume is expected to reach 165 million tonnes per annum following the completion of construction.

Project Description

Quickway was engaged on this project to construct two rail bridges. The scope of our works included:

  • Black Creek Underbridge
  • Lochinvar Station Footbridge


Number of Bridges: 2 single span bridge – 20m

Number of Bridge Construction Concurrently: 1

Type of Bridge: Underbridge and footbridge (rail)

Type of Superstructure: Girders with transverse precast concrete slab and topping in-situ slab

Type of Substructure: In- situ abutments on bored piles

Type of Parapets: Precast parapets with in-situ stitch pour

Key Challenges

  • Working within the rail corridor: Engagement with ARTC to work within allotted time frames and parameters.
  • Work was completed in close proximity to the Black Creek River, and controls were put in place to prevent any environmental impacts through development of the site CWEP and review of the local protected species of flora and fauna.
  • Deadlines to coincide with the other ARTC work packages.
