Nelson Bay Road Upgrade

Completed Projects

In July 2013 Ferrovial Agroman (Australia) was successful in winning the contract with the New South Wales Roads and Maritime Services (RMS) to upgrade 4.2 Km of Nelson Bay Road, the longest section of the upgrade to dual carriageway between Bobs Farm a Anna Bay. It will involve reconstructing the existing carriage way and Constructing a second carriageway between Cromarty Lane, Bobs Farm and Port Stephens Drive roundabout, Anna Bay.

Location

Nelson Bay, NSW

Nelson Bay Road is a State Road and the main arterial link connecting Newcastle to Williamtown and the Tomaree Peninsula. It carries a large volume of local and tourist traffic visiting the Nelson Bay area as the only route servicing the Tomaree Peninsula and the various townships between Newcastle and Nelson Bay.

The main project features are:

  • Constructing a second carriage way between Cromarty Lane and Port Stephens Drive roundabout at Anna Bay.
  • Reconstructing the existing carriageway Landscaped median to separate opposing traffic.
  • Ten upgraded bus bays.
  • New u-turn facilities to provide safe access to properties along the route Pedestrian refuges in the median adjacent to bus bays.
  • Wider shoulders and improved intersections.

These all features will give many benefits to communities around, such as improve on safety for motorists, cyclists and pedestrians; better bays for bus passengers; reduction in traffic delays and more reliable travel times for motorists using this section of Nelson bay Road.

WORKING WITH SAND

Nelson Bay Road Upgrade is located less than five kilometers from the Stockton coastal barrier dune system and more than fifty kilometers away from more conventional sources of earthworks such as borrow pits or quarries.

Although Roads and Maritimes Services of NSW Government (RMS) has developed procedures to construct embankments with sand from the coastal dune, the placing of this material represents some difficulties such as moving on top of the surface with trucks.

To avoid risks and facilitate the works, these embankments require consolidated dock areas where the trucks can tilt up and then a dozer push the sand forward. These dock areas need to be constructing every 100 m using certain unbound material from quarry. The main method of compaction is by flooding with water. A geotextile in some situations can be needed to confine the sand regarding upper layers as the select material.

LOCAL FAUNA

The Port Stephens area has been identified as one of the richest koala sites in the State of New South Wales, and the Tilligerry Peninsula, which is adjacent, that’s why the project contains prime habitat for this species, one of the state’s last viable populations.

Although many eucalypt trees grow in Australia, only a few are suitable for koalas, the Swamp Mahogany and Forest Red Gum, from which koalas will absorb most of the moisture that they need from Eucalyptus leaves, rarely coming down from the trees to drink.

Koalas are classified as “vulnerable and rare” species, and local authorities have developed a Koala Management Plan to address some of the dangers which the face. Being slow movers, some of the most pressing dangers to them include domestic dogs and speeding cars.

Said that, transversal connectivity through the new motorway for Koala and other species is provided by fauna underpasses and rope bridges. To assist in ensuring fauna to use the facilities, floppy tops fencing will be installed along the project boundary.

A great collaboration is received from National Parks, who are glad with our environmental measures and monitoring of the fauna and flora. As example of these measures; we are relocating more than 280 nests using wooden nest boxes; equally we are providing treatment along the alignment to eliminate noxious weeds such as “Chinese Violet and the Alligator weed, both class 1 noxious weeds”. As result of this good relationship, National Parks are collecting all our mulch production from the clearing and grubbing for future reuse and recycling.

PROJECT COMPLETION

On the 18th May 2015, The Nelson Bay Road Upgrade Project, Ferrovial's first project in Australia was officially opened by The NSW Minister for Roads, Maritime and Freight - Hon. Duncan Gay and Parliamentary Secretary for the Hunter and Central Coast, Scott MacDonald. " The upgrade was funded though the NSW Government's Hunter Infrastructure and Investment Fund and will improve road safety and provide more reliable travel times for the 7,000 motorist using this road each day when travelling between Newcastle and Port Stephens," Mr Gay said.
