Light Horse Interchange M7

The Australian Light Horse Sculpture Parade is dedicated to the heroic troops who served in the Australian Light Horse and their horses that could never return. The lit mast and crown symbolise a torch in the dark. Red, the colour of the Flanders poppy and poppies that bloomed throughout Palestine, is symbolic of the blood of supreme sacrifice and is the colour chosen for the sculpture. 

Westlink M7 is one of NSW largest tolled motorways, operated by Transurban, constructed by Leightons Abigroup JV. It was opened in 2007 completing a major section of Sydney's Orbital stretching 40km across Western Sydney. It includes a separate 40km, 4m wide shared path. Colin was project leader for the urban design as an Associate of Conybeare Morrison and designed all visible components of the $1,5 billion project.
