Night road closures along the M4 at The Northern Road

Monday 9 July 2018

Motorists are advised of changed traffic conditions along the M4 Motorway from Friday 13 July to 10 August for continuing night road work to build a new interchange across the M4 at The Northern Road in South Penrith.

A Roads and Maritime Services spokesperson said detours would be in place for traffic in both directions via the M4 Motorway entry and exit ramps to The Northern Road.

During the night work, the M4 Motorway will be closed in both directions for 14 nights, between Friday 13 July 2018 and Friday 10 August 2018, weather permitting:

  • Monday (Tuesday mornings) to Thursday (Friday mornings) from 10pm to 4am
  • Friday nights (Saturday mornings) from 10pm to 7am
  • Saturday nights (Sunday mornings) from 10pm to 8am Motorists should plan their trip, allow extra travel time and follow the direction of traffic control and all signs, including a reduced to 40 km/h speed limit through the work zone.

Motorists travelling at this time could consider alternative routes including the Great Western Highway.

Electronic message signs and traffic controllers will be in place to direct road users through the work site.

Roads and Maritime Services is also working to minimise impacts on local residents by using equipment fitted with noise mitigation devices, locating machinery away from residents where possible and turning it off when not in use, and monitoring noise at night.

The community is thanked for its patience during this work.
