Updates and announcements

Traffic changes

Motorists are advised of changed traffic conditions from next week on the New England Highway south of Tenterfield as part of the Bolivia Hill upgrade project.

Work will be carried out from Monday 4 February on the eastern rock face adjoining the highway, about 35 kilometres south of Tenterfield, and is expected to take three months to complete, weather permitting.

The highway will be reduced to one lane between 6am and 6pm, from Monday to Saturday, with delays of 10 to 15 minutes expected.

Traffic control and a reduced speed limit of 40km/h will be in place for the safety of workers and motorists.

Motorists are advised to drive to the conditions, and follow the direction of signs and traffic control.

Roads and Maritime Services thanks motorists for their patience during this time.

Work continues on site

Early work activities are continuing with clearing and installing access tracks. Motorists are also advised of intermittent traffic changes over the next few months to allow a number of activities to take place along the highway.

Work will also be carried out to widen the intersection of Pyes Creek Road to improve safety for workers turning in an out of the road during construction. Access to all properties along this section of highway will still be available during this time.

The speed limit within the work zone will be reduced to 40km/h while the work is being carried out and motorists are advised to follow the direction of traffic controllers and lights in place.

Work hours

Work will be carried out between 7am and 6pm from Monday to Friday and between 8am and 1pm on Saturday.

Nearby residents will be advised of any construction work outside normal working hours as soon as possible.

The preferred route for the Bolivia Hill upgrade will:

  • Improve road safety
  • Improve road transport productivity, efficiency and reliability of travel

Bolivia Wattle seed collection

Seedlings of the rare and endangered Bolivia Hill Wattle have been collected and delivered to Mount Annan Botanic Gardens for preservation. The unique wattle was identified during the review of environmental factors for the planned upgrade of the New England Highway at Bolivia Hill.

The discovery provided an opportunity for Roads and Maritime Services to work with the local community to gather and store seeds. Five people from the Inverell Aboriginal Men’s Group were trained to monitor the wattle to ensure the seeds were suitable for collection and then later, planting.

The wattle is unique to the area, growing only between Bolivia Hill and Glen Innes and Tenterfield, so it’s important to preserve it for future generations.
