The intersection of Parkes Way and Kings Avenue forms a significant gateway to the Central National Area from the east and in particular from the airport. The design plays down the intersection in the view along Kings Avenue while using the bridge to celebrate the arrival experience on the Parkes Way approach.

A single point urban interchange was identified as the most efficient traffic model. This model is reflected in the form of the bridge, with large curved wing walls retaining the bridge abutments and flowing across the bridge to intersect with grassed and tree-lined embankments on either side of Parkes Way.

This project delivers engineering excellence as much for its ingenuity of design that seeks to complement and enhance Canberra’s National Triangle, as it does for the management of a complex construction around the busy operation of the intersection.

JPW have taken a brief of re-developing an intersection and re-instating views to create, in spades, a thoroughly resolved, highly functional solution. Passage through this once alarmingly dangerous crossroad, known as ‘ Russell Roulette’, is now a joy, be it on foot, bicycle, car or, as the project has future scope for, light rail.

Jury Citation, 2012

The Griffin Legacy project aimed to realise unfulfilled aspects of the original Griffin Plan for Canberra, culminating in a vision document published in 2004. The lowering of Parkes Way has transformed it from a barrier into a connector, providing safer and more direct access to Lake Burley Griffin and the central parklands from Russell via the new bridge. With the removal of the roundabout, the focus of the Kings Avenue vista now highlights the base of the triangle at Russell, reinforcing the intended geometry of the Parliamentary Triangle.
