Gungahlin Drive improvements

Project background

Gungahlin Drive had previously experienced considerable congestion, particularly during peak periods, as traffic accesses the Mitchell commercial and industrial precinct. This traffic congestion was expected to increase as the Gungahlin Town Centre and greater Gungahlin area continued to grow.

In late 2014, engineering and development consultants SMEC were commissioned to undertake traffic modelling and analysis for a range of potential upgrades on Gungahlin Drive. This analysis found the best way to address congestion issues was to add an additional southbound lane and complete intersection upgrades on Gungahlin Drive from Well Station Drive to the Barton Highway.

Scope of works

Works involved the construction of an additional southbound lane on Gungahlin Drive from approximately 500 metres north of the Sandford Street intersection through to the Barton Highway off ramp. The widening predominantly occured in the median.

Minor works at the Well Station Drive/Gungahlin Drive intersection signalised the left turn out of Well Station Drive and provided a second left turn lane.

Other works included new and relocated street lighting, adjustment to the shared path south of Sandford Street and stormwater system adjustments.

Community consultation

Information on specific construction impacts were provided on electronic roadside signage as well as through other preferred communication methods identified by the community including website information.


Construction was completed in mid-2016.

Traffic impacts

  • The on-road cycle lane between Well Station Drive and the Barton Highway was closed during the widening works, with cyclists detoured onto existing off-road shared paths (on the western side of Gungahlin Drive between Well Station Drive and Sandford Street and on the eastern side of Gungahlin Drive between Sandford Street and the Barton Highway).
  • The speed limit was reduced between Sandford Street and the Barton Highway exit to ensure the safety of construction workers.
  • Temporary lane closures were scheduled outside of the morning peak period.

Note there are numerous projects on arterial and major roads in Gungahlin that are scheduled to be under construction at the same time and the ACT Government would like to thank motorists for their patience while these important works are undertaken.
