Intersection improvements on Cumberland Highway and Merrylands Road, Greystanes

The NSW Government is funding this work as part of its $300 million Urban Roads Pinch Points Program which aims to reduce congestion and improve travel times on Sydney’s busiest corridors.

Project background

Roads and Maritime Services will carry out utility survey and investigation works including potholing, cutting and reinstating the road pavement. To minimise impacts on traffic and to ensure the safety of workers and road users, some of this work will be carried out at night.

The work will take place at the intersection of the Cumberland Highway and Merrylands Road, Greystanes.

The investigation work will be carried out between 24 August 2017 and 8 October 2017, weather permitting. Our night work hours are from 9pm to 5am between Sundays and Thursdays. We expect the night work to take approximately 5 shifts to complete, weather permitting.

Some work may also be carried out during the day. Our day working hours are from 7am to 6pm between Mondays and Fridays.

The proposal includes:

  • Installing dual right turn lanes east and westbound on Merrylands Road and northbound on Cumberland Highway
  • Removing the existing traffic island on Merrylands Road at the southeast corner of the intersection
  • Modifying the westbound bus bay on the southern side of Merrylands Road
  • Installing barriers along the southbound carriageway of Cumberland Highway on the south east corner of the intersection
  • Adjusting the central road medians on all approaches of the intersection to accommodate the new turning lanes
  • Aligning the westbound left turn slip lane on the Cumberland Highway to accommodate the new intersection layout
  • Adjusting the existing traffic signals to support the new intersection
  • Adjusting footpaths and kerbs
  • Trimming and removing trees and shrubs.

Benefits would include:

  • Reduced congestion and improved travel times in both the AM and PM peak periods
  • Improved traffic flow on Cumberland Highway and Merrylands Road
  • Improved safety for pedestrians and road users.

We have included a map to show the location of the proposal.

How will the work affect you?

There may be some noise associated with this work, but we will complete it as quickly as possible to minimise any disruption and complete the noisiest works before 11pm.
