Updates and announcements

From 28 June until 1 July 2016, Roads and Maritime Services will be undertaking geotechnical surveys of the Tompsitt Drive and Lanyon Drive intersection.

Work will be carried out Tuesday to Friday between 7am and 5pm, weather permitting. Peak traffic flows will be unaffected during these investigations.

For the safety of motorists and workers, lane closures will be in place during the investigations and a reduced speed limit of 40km/h will apply. Motorists should allow an additional 5 minutes travel time during work hours.

Please keep to speed limits and follow the direction of traffic controllers and signs. For the latest traffic updates, you can call 132 701, visit or download the Live Traffic NSW App.

Next steps

The results of the geotechnical surveys will help to inform the planned intersection improvements.

Other surveys to be conducted include collection of updated traffic counts and modelling with consideration of expected growth in the area.

Roads and Maritime Services will update the community regarding next steps on the intersection improvements by October 2016.

Project background

The intersection of Tompsitt Drive and Lanyon Drive in Jerrabomberra is located on one of the major access routes into the Australian Capital Territory.

This intersection features a roundabout with dual lanes on each approach and a left slip lane on the west bound approach. The intersection is currently performing poorly with motorists experiencing traffic delays and queuing, particularly during peak times.

In March 2015, the NSW Government announced $5 million in funding towards improvements at this intersection, with completion of construction expected by December 2018.

To determine the most effective design for the improvements Roads and Maritime Services will carry out investigations including traffic modelling, consideration of traffic growth in the area and geotechnical surveys.

Project benefits

  • Reduce the significant queuing being experienced by motorists during peak times
  • Reduce traffic delays for motorists travelling through the intersection
  • Improved road safety at this intersection.
