Trimble has announced that it has been selected as the preferred supplier of machine control and survey equipment for Thiess John Holland, the lead contractor building Australia’s largest road project¯EastLink in Melbourne. Trimble works in the field of GPS technology. With total construction costs of AU$2.5 billion (US$1.9 billion), the scale of work required for timely completion of Melbourne’s EastLink is beyond that ever tackled before on any single infrastructure project in Australia.

EastLink’s three-lane, freeway-standard road is expected to be built over three and a half years. Construction includes two million square meters of paved road, more than eighty bridges, seventeen interchanges and 1.6 kilometers three-lane twin tunnels. The project will deliver Melbourne’s second fully electronic tollway, comprising about 45 kilometers of freeway-standard road connecting the city’s eastern and south eastern suburbs. Connecting the Eastern Freeway in Melbourne’s east to the Frankston Freeway in the south-east, EastLink is expected to become a major commuter road and a key intracity arterial route.
