Updates and announcements

Night work from Sunday 18 November

Night work will be carried out to resurface the road around the temporary roundabout.

Work will be carried out from 7.30pm to 6am, Sunday night to Saturday morning, from Sunday 18 November until Saturday 1 December, weather permitting.

Traffic control, speed reductions and alternating traffic flow will be in place for the safety of workers and motorists.

Motorists are advised to allow additional travel time, 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.

Construction update

Roads and Maritime Services has moved to the next stage of major construction of the intersection upgrade on Lanyon Drive and Tompsitt Drive, Jerrabomberra.

This is a substantial road project and traffic changes are required to be in place during construction to ensure the safety of all road users.

Following feedback in early October, a new traffic management plan for this stage of work has been fully implemented. The revised traffic management plan will now deliver the best outcomes for road users and will provide acceptable traffic flows for motorists during morning and afternoon peak times.

For the safety of workers and motorists, a reduced 40 km/h speed limit and changed traffic conditions will be in place during off peak times, from Tuesday 6 November.

These changes include the installation of a smaller temporary roundabout at the intersection which will feature a dual right turn into Tompsitt Drive for afternoon peak flows and a continuous left slip lane out of Jerrabomberra in the morning.

All other movements through the intersection will be enabled during peak times without diversions in place.

Motorists are advised to drive to the conditions, allow additional travel time during peak hours and follow the direction of signs and traffic controllers.

Work on the upgrade is expected to be completed by the end of 2019 weather permitting.

Roads and Maritime Services would like to thank the community for raising their concerns. We are working closely with our contractors to monitor traffic conditions.

For more information regarding the upgrade please contact the project team on 1800 727 714 or email southernprojects@rms.nsw.gov.au.

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.

The upgrade at this intersection involves replacing the existing roundabout with traffic lights to reduce congestion for motorists who travel through it during peak times. The upgrade will also provide better facilities for pedestrians and cyclists.

Guideline ACT has been appointed to build the new intersection.

Project benefits

  • Reduce the significant queuing being experienced by motorists during peak times
  • Reduce traffic delays for motorists travelling through the intersection during peak times
  • Improved road safety for all vehicles
  • Improved amenity for pedestrians and cyclists
  • Provides for future traffic growth.

Next steps

Work on the upgrade is expected to be completed by the end of 2019 weather permitting.

Roads and Maritime will keep the community updated as the project progresses.
