NBHR Project Milestone

Local news

Congratulations to the Northern Beaches Hospital Roadworks (NBHR) team for achieving two major milestones: theTraffic Switch on Warringah Road and reopening Frenchs Forrest and Naree Roads to two-way traffic.

The NBHR upgrade project is being undertaken by Ferrovial Agroman in Australia, in a very demanding urban environment, surrounded by more than 200 residences, 6 business parks and 2 adjacent schools. The works involve the upgrade and widening of four major arterial roads, which require careful planning and consultation. This year, the project successfully implemented two major traffic changes and delivered on key project milestones.

Traffic Switch on Warringah Road (Stage 2)

The first of the two major milestones along the Warringah Road westbound carriageway commenced in 2015. The upgrade came with many challenges, including maintaining the existing road occupancy for more than 120,000 vehicles daily whilst delivering on the following:

  • Bulk earthworks and pavement works
  • Installing new stormwater drainage, detention tank, traffic signals, a bus stop, handrail capping beams, concrete barriers
  • Removing and relocating underground services
  • Demolishing an old pedestrian bridge, piling for and installing two new pedestrian bridges
  • Installing 300m of retaining wall with soil nails and shotcrete, noise walls along properties adjacent to Warringah Road, a shared user path, property works, line marking and landscaping
    Once complete, the permanent switch of westbound traffic to the new westbound carriageway occurred. The following weekend, the Warringah Road eastbound traffic moved over to the old westbound traffic lanes, allowing for the upgrade to the old eastbound carriageway to commence.

Reopening Frenchs Forest and Naree Roads to two-way traffic (Stage 1)

The second major project milestone was successfully met through the hard work and determination of the project team. Running parallel to Stage 2, Frenchs Forest and Naree Roads carry 20,000 vehicles a day and has been widened from two to four lanes of traffic. Since Oct 2017, the following activities have taken place:

  • Milling and pavement rehabilitation
  • Constructing new kerbs, gutters and footpaths
  • Relocating utilities, temporary bus stops
  • Installing and commissioning new traffic signals
  • Installing street furniture
  • Ongoing traffic changes and detours
  • Landscaping

In July, Frenchs Forest Road and Naree Road reopened to two-lane, dual carriageway traffic.

These two key project milestones involved detailed planning and an enormous effort from everyone involved. With many more major milestones ahead, the NBHR project team will be required to further contribute their efforts, experience and expertise to deliver first-class infrastructure for Sydney.
