Northern Road Upgrade, NSW

Connolly EXJ Expansion Joints have assisted contractors complete 18km of shared path for a Transport for New South Wales major infrastructure project, using high-productivity continuous concrete pour techniques.

The Northern Road and Bringelly Road Stage 2 Upgrade Project for Transport for New South Wales is a key element of the Western Sydney Infrastructure Plan, increasing road capacity ahead of the new Western Sydney airport development.

The Project has provided intersection upgrades and dual carriageway to more than 15km of roadway, improving safety and cutting journey times for more than 25,000 motorists.

The Challenge

One of the challenges faced by the Principal Contractor ACCIONA was to pour the 8,100 cubic metres of concrete over 18 kilometres for the shared path within a timeframe that met the overall Project program requirements.

The Solution

To assist in meeting the Project program, ACCIONA’s subcontractors adopted a solution which utilised Connolly EXJ Expansion Joints.

The leave-in-place expansion joints were quick and easy to install using the Connolly patented ‘peg and wedge’ system. They provided 10mm expansion across the full depth of the slab and allowed the contractors to pour concrete continuously to both sides of the joint, instead of using the more common ‘chequerboard’ approach.



RiFL Hub, Wagga Wagga NSW

For Absolute Mesh and Steel, supplier to Huon Contractors Pty. Ltd., their job to install a concrete intersection pavement for Wagga Wagga City Council, was completed with no major hiccups, despite being regionally located.

The Riverina Intermodal Freight and Logistics Hub (RiFL) is a significant upgrade to the agricultural Riverina region of southwestern New South Wales. It covers an area of 80,545 sq km and services a population of 173,593 people from Wagga Wagga and Griffith cities and local government areas. With freight volumes expected to double over the next 15 years, this Logistics Hub is vital to the region’s growth, creating jobs and boosting productivity.

As part of the industrial sub-divisions Stage 3 development, Huon Contractors Pty. Ltd. installed a concrete intersection pavement. Working with the local supplier, Absolute Mesh and Steel, Leviat was able to manufacture and supply custom 33mm galvanised Connolly Round Dowel Cradles to facilitate the Contractor’s program. Using Connolly Dowel Cradles meant installation was quick, and load could be transferred sufficiently in saw-cut contraction joints.

In their most basic form, Dowel Cradles are a welded wire assembly that ensures horizontal and vertical alignment of dowels at the correct spacing and height necessary for the application. As commented by the customer, “Dowel Cradles seemed like the only way to complete this job. They meant quick and easy joint setup with minimum fuss.”

The installation of concrete intersection pavement for Wagga Wagga City Council was completed without major hiccups, thanks to the use of local resources and working with the wider community.
