Route Overview:

Commonwealth Ave is the backbone of road transport in Canberra, crossing Lake Burley Griffin from the CBD to Parliament House. The route was constructed properly in the 1930's, prior to then the road had existed as no more than a track. When the lake was constructed in the 1960's the spectacular twin bridges were constructed, opening to traffic in November 1963. It was at this time that the entire road was duplicated.
