Updates and announcements

Construction update – April 2019

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

The temporary roundabout will be removed and most of the new traffic signals will be installed and switched on in a temporary arrangement while work continues. The signals are expected to be in operation from the morning peak traffic period on Wednesday 10 April, weather permitting.

Motorists should allow additional travel time. Roads and Maritime will closely monitor traffic conditions and signals.

Some lanes will remain closed and pedestrian facilities will not be open until the full commissioning of the signals closer to project completion. Traffic signals will be adjusted to allow for peak traffic flows during the final stages of construction.

Work will continue to increase road levels and install footpaths. Work remaining includes building concrete median islands, line marking, landscaping and installing additional traffic signals and lighting.

Our work hours are 7am to 6pm, Monday to Friday.

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.

Please drive to the conditions and follow the direction of signs and traffic controllers.

Work on the upgrade is expected to be completed by mid to late 2019, weather permitting.

We are working closely with our contractors to monitor traffic conditions as the project progresses.

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.
