Westconnex Road Closure and Traffic Updates

Friday, 12th May, 2017

Utility services work – Carrington Lane, North Strathfield

Work is underway on WestConnex which involves widening and extending the M4 and M5 and joining them to create a free-flowing motorway network.

The M4 East will extend the existing M4 from Homebush to Haberfield via underground twin tunnels, each 5.5 kilometres in length and among the widest in the southern hemisphere. They will allow for three lanes of traffic in each direction, saving travel time for motorists and taking traffic off local roads. For more information, visit westconnex.com.au/m4east.

From Monday 15 May 2017 work will be required to investigate and repair sewer services on Carrington Lane, North Strathfield. A map of the work area is provided overleaf.

Work will be undertaken during standard construction hours of 7.00am to 6.00pm, Monday to Friday and 8.00am to 1.00pm on Saturdays. The work is expected to take up to ten days to complete, weather permitting, and will include:
● installing temporary worksite and fencing
● service investigation and potholing
● trenching the road and footpath
● installing PVC pipes
● backfilling and temporary reinstatement of work area.

The temporary closure of Carrington Lane will be required at the eastern end (near Concord Lane) to facilitate this work. Traffic control and pedestrian management will be in place to ensure the safety of motorists, residents and workers. Please allow extra travel time and follow the signage and the direction of traffic controllers.
Equipment used during the work will include vacuum trucks, concrete saw cutters, jackhammers, light vehicles and hand tools.

There may be some noise associated with these works, however every effort will be made to minimise the impact of work, including by using non-tonal reversing beepers on all machinery, turning off equipment and vehicles when not in use and, where possible, directing noisy equipment away from residences.

Ground water monitoring wells – Parramatta Road, Ashfield

Work is underway on WestConnex which involves widening and extending the M4 and M5 and joining them to create a free-flowing motorway network.

The M4 East will extend the existing M4 from Homebush to Haberfield via underground twin tunnels, each 5.5 kilometres in length and among the widest in the southern hemisphere. They will allow for three lanes of traffic in each direction, saving travel time for motorists and taking traffic off local roads. For more information, visit westconnex.com.au/M4East.

In order to monitor ground water levels associated with M4 East tunnelling activities, monitoring wells will be installed across the project.

From Saturday, 13 May 2017, installation of ground monitors will be undertaken within the property of 252 Parramatta Road, Haberfield.

Work will take place between 7.00 am and 7.00 pm on Saturday, 13 May and Sunday, 14 May 2017, plus two contingency shifts. Only site mobilisation and demobilisation work is permitted to be undertaken between 7.00 am and 8.00 am and 6.00 pm and 7.00 pm. Notification will be provided if the contingency shifts are required.
The work will take two shifts to complete, weather and site conditions permitting, and will include:

  • establishing a temporary work site
  • excavating a small hole to confirm the location of underground services, such as pipes and cables
  • drilling and grouting to install the monitoring equipment
  • installing a flat, protective cover over the equipment.

Once installed, the monitoring equipment will remain in place for a minimum of three and a half years. A technician will check the equipment regularly. Following the completion of monitoring activities, the site will be restored to its original condition.

There will be some noise associated with this work, however every effort will be made to minimise the impact of work, including by using non-tonal reversing beepers on machinery, turning off equipment and vehicles when not in use and, where possible, directing noisy equipment away from residences.

Piling activity on M4 Motorway near Short Street, Homebush

Work is underway on WestConnex which involves widening and extending the M4 and M5 and joining them to create a free-flowing motorway network.
The M4 East will extend the existing M4 from Homebush to Haberfield via underground twin tunnels, each 5.5 kilometres in length and among the widest in the southern hemisphere. They will allow for three lanes of traffic in each direction, saving travel time for motorists and taking traffic off local roads. 

From Wednesday, 10 May 2017, piling activity will commence along the M4 Motorway, Homebush. The work is expected to take three nights to complete. A map showing the work area is provided is attached.

This work will take place between 10.00 pm and 5.30 am to reduce impacts on road users and ensure the safety of workers and motorists. If the work cannot be completed during this period, it will be rescheduled.

Temporary closures of the M4 Motorway will be in place during this night work. Please allow extra travel time and follow the signage and the direction of traffic controllers.

Equipment used throughout the work will include a piling rig, excavators, cranes, light vehicles, traffic control, generators, lighting towers, power drills, and trucks.
There may be some noise associated with this work, however every effort will be made to minimise the impact of work, including by using non-tonal reversing beepers on all machinery, turning off equipment and vehicles when not in use and, where possible, directing noisy equipment away from residences.

Tunnelling progress update – Underwood Road construction site

The first of two roadheaders operating from the Underwood Road construction site commenced tunnelling in August 2016, with the second roadheader launched in September 2016. Both of these roadheaders are tunnelling in an easterly direction to construct the eastbound and westbound tunnels of the M4 East.

In accordance with the conditions set out by the project’s Environmental Protection Licence, tunnelling activities including excavation will occur 24 hours per day, seven days per week.

Excavated rock and material will be stored in the acoustic shed to be removed from the site during standard construction hours of:

  • 7.00 am to 6.00 pm Monday to Friday
  • 8.00 am to 1.00 pm on Saturday

Due to an increase in the amount of construction materials required, limited 24-hour access to the site by delivery trucks commenced in December 2016.

Tunnelling activities near your property

Tunnelling and related construction activities will commence near your property between May 2017 and June 2017. The schedule and a map showing the approximate location of upcoming tunnelling activity is provided below.

What to expect during tunnelling

Each individual’s experience of tunnelling may vary due to a range of local conditions and variables. Vibration and noise levels experienced depend on ground conditions, building types, existing background noise levels and the quality of your property (older buildings were built to different standards than newer buildings). It also depends on how far away you are from the tunnel. In some instances, you may experience the following:

  • Ground borne noise – this is created when vibration from tunnel excavation travels through the ground and causes a building’s flat surface to vibrate, occasionally creating an audible ‘rumbling’ noise.
  • Vibration – at times you may feel some vibration, however the predicted levels are not high enough to cause damage to property. Once the tunnel is complete, you are unlikely to hear or feel any vibration from vehicles using the motorway.

For more information about tunnelling methodology please see the attached fact sheet.

Drainage work – Queen Street, North Strathfield

Further to our notification on 24 March 2017 (N186), work will continue along Queen Street, North Strathfield to install new drainage associated with the Concord Road Interchange work. A map showing the location of the work is provided overleaf.
