Lane Management System (Tidal Flow)

The NSW Government is taking action to deliver transport improvements for the Northern Beaches and Lower North Shore, including an integrated program of service and infrastructure upgrades.

Throughout the coming months, work will take place to install a new lane management system (tidal flow), relocate existing underground services and upgrade the road from Mosman to Neutral Bay.

Over this period, current lane and parking arrangements will change to accommodate these works.

What is a tidal flow lane?

This is a ‘reversible’ lane in which traffic may travel in either direction depending on the time of day or traffic conditions. It is designed to improve traffic flow during peak periods by making an extra lane available for vehicles travelling along the busier side of the road.

Typically, a combination of movable medians, candy bar bollards, and in-pavement lights are used to separate the traffic travelling in opposite directions and to show the live lane configurations when we can.

What to expect

These works will include noisy activities and noise mitigation measures will be in place to minimise disruption for nearby residents. These measures are part of the project’s Construction Noise and Vibration Guidelines (CNVG). Some ways in which the project team try to reduce the impacts of the work include:

  • the use of barriers and sound blankets to help reduce noise impacts
  • the use of non-tonal reversing alarms (also known as squawkers) instead of beepers on vehicles
  • carrying out noisier activities such as jackhammering and saw cutting earlier in the shift, where possible
  • directing the lights away from residents
  • talking to directly impacted residents before the work starts to let them know what to expect.
