1912 年堪培拉的设计竞赛中，Walter Burley Griffin 和 Marion Mahony Griffin 二人提出了提升城市街头潜力的想法，他们希望澳大利亚的街道能够与场地产生深度的共鸣，具有自然的敏感性和对民主社会的理解。

In the 1912 competition winning scheme for Canberra, Walter Burley Griffin and Marion Mahony Griffin presented the potential power of streets, proposing a city of avenues that demonstrated a deep resonance with the site, sensitivity to nature and a clear and precise understanding of and vision for Australian democratic society.

这处城市路网中最引人注目的区域是 Grand Boulevard 大道，也被称之为 Constitution Avenue 宪法大道。街道的建设效仿了世界上最大的林荫大道，将承载城市中密度最高的商业和住宅区的基础交通。同时，Lake Burley Griffin 附近的娱乐和文化建筑区域也会在这个大道旁选址建设。

The crowning piece of this street network was to be the Grand Boulevard, or Constitution Avenue, as it is now known. Modelled on the world’s greatest boulevards, it will be the city’s high street and premier address with the highest density of commercial and residential buildings, while also providing an address for some of the main cultural buildings of the recreation areas adjacent to Lake Burley Griffin.

设计团队对格里芬街道系统 (Griffin’s Avenue system) 的应用，不是简单的怀旧，而是对城市发展一种远见卓识的考量。作为一个城市尺度的项目，这个大道具有彻底改革堪培拉生活方式的潜力：改善步行体验、驾驶舒适度，包括承载高容量的过境交通，同时良好的居住环境可以改善市民的公民素质的堪培拉市中心的运作方式。就像是巴黎的香榭丽舍大道或者华盛顿的宾夕法尼亚大道一样，堪培拉的宪法大道也会成为让世界难忘的林荫大道景观之一。

Our team realised Griffin’s Avenue system and Grand Boulevard, which is by no means nostalgic but remains visionary. As an urban project it possesses the potential to overhaul the way Canberra is traversed – improving the pedestrian journey, the driving experience, the potential to include high capacity transit modes as well as greatly improving the civic character and functioning of central Canberra. Just like Paris’ Champs-Elysses or Washington’s Pennsylvania Avenue, Constitution Avenue’s successful upgrade establishes it as one of the memorable urban boulevards and vistas of the world.
