Constitution Avenue upgrade

Project background

Constitution Avenue is a 2.5 kilometres road reserve connecting Vernon Circle in the city through to Northcott Drive in Russell. Before the upgrade, the road started at Knowles Place, the access road to the Legislative Assembly car park.

The Constitution Avenue Upgrade project provided major public transport, infrastructure and landscape improvements for the community, between Vernon Circle and Wendouree Drive.

Scope of works

The upgrade included:

  • 1.6 kilometres of upgraded road construction, providing dual carriageways, and streetscape improvements, between Vernon Circle and Wendouree Drive
  • a dedicated bus lane in each direction from Allara Street to Anzac Parade
  • connection to Vernon Circle
  • Parkes Way to Allara Street connection
  • high quality pedestrian facilities and public realm
  • a separated two way cycle path in the southern verge
  • high quality pedestrian facilities and public realm
  • a separated two way cycle path in the southern verge
  • tree replacement of a significant number of the aging English Oak Trees with 261 trees planted along the full limits of the upgrade works
  • new LED street and verge lighting for the length of the project.

The long term vision for Constitution Avenue has always been to act as more than a strategic corridor; more so one which delivers a vibrant, mixed-use, tree-lined grand avenue with enhanced public transport, cycling and pedestrian movement.

As commercial and residential development is progressed along Constitution Avenue, the public realm spaces will be upgraded to achieve the visionary design for 2031. This upgrade has ensured the necessary streetscape infrastructure is in place to support this vision.

Project funding

In celebration of the Centenary of Canberra, the Australian Government gifted $42 million to the ACT Government for the upgrade of Constitution Avenue.

Community consultation

Community consultation with adjoining owners and business operators as well as the general public was undertaken in 2012. Discussions with the owners and business operators are ongoing throughout the construction phase.


Major construction was completed in August 2016.
