Marino Rocks Greenway ANZAC Highway Underpass

The Marino Rocks Greenway provides a safe, direct, continuous and attractive link from the City to the southern suburbs
of Adelaide. The underpass beneath the heavily trafficked Keswick Bridge connects the existing Anzac Hwy/West Tce shareduse path in the Adelaide Parklands with the existing path adjacent the Adelaide Showground, effectively creating a
continuous bike path that now runs from the city centre to the Marino Rocks beach precinct some 15km to the South West.

The full scope of works included bulk earthworks, the construction of a retaining wall involving bored piles and a pre-cast concrete wall. The shared path totals 306m in length and 3m wide and accommodates both pedestrians and cyclists.

The project posed many challenges including the existing levels on the drawings not matching those on site and drainage of the pavement not being accounted for in the original design, but was successfully completed with zero lost time or medical treatment injuries throughout the 9,600 man hours recorded.
