Updates and announcements

Roads and Maritime has investigated various upgrade options to develop a preferred option based on a range of technical, environmental and social considerations.

The proposed upgrade would replace the existing roundabout with traffic lights to reduce traffic congestion and cater for future traffic growth.

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.

To determine the most effective design for the improvements Roads and Maritime Services has been carrying out investigations including collection of traffic counts, ground and utility surveys, geotechnical investigations and detailed traffic modelling with consideration of expected growth in and around the area.

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
  • Provides for future traffic growth.

Next steps

The next step for the project will be detailed design and environmental assessment. This will have more detailed information about the design features, identification of impacts and their management during construction.

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