Over the last month, work has involved pavement construction, bridge upgrades, service protections,locations, and various retaining walls.

The safe work zones are in place between Hill Road to Takanini Interchange:and the Pahurehure Inlet.

• Continued offsite precasting components for retaining walls, noise walls, and bridges.

Over the next month, we will continue working in the median and shoulders between Hill Road and the Pahurehure Inlet. We will also continue working to widen the motorway bridges over the Papakura StreamStream, and the KiwiRail Lines. WeLines. Service investigations will utilise opportunities tocontinue for future work on the northbound side of the motorway, however, our focus remains on the southbound side. This will ensure we achieve our goal of an additional lane from Hill Roadareas to north of the Pahurehure Inlet (excluding the Takanini Interchange) by the end of March 2017.be established, including works around major utilities such as gas, water, and power main lines. Work this month includes:

  • Across the project, long term environmental controls are being installed to maintain water quality during construction.

   

  With the lanes narrowed, there is less time to react to other vehicles and  itIt is important that motorists keep to the 80 km/h speed limit past our work areas. There will be ongoing truck and project vehicle movements accessing the shoulder and the median work sites. Keeping both motorists and our team members as safe as possible is imperative and we need everyone's help to do this.

  As always, we will be doing our best to minimise effects of these works on motorists as much as we can. We thank you for your patience as we work to improve journey reliability and safety along the Southern Corridor.
