Prior to the 1850s inland travel was generally along cart tracks but, following the gold rushes, the road to Mount Macedon and Ballarat was a busy thoroughfare of diggers passing on their way to the goldfields and was one of Victoria's most important inland roads. Swamp land around Rockbank made the route along Greigs Road the most practical early route to the Ballarat and later Blackwood (Ballan) diggings.
The route followed the Greigs Road alignment (at that time known as Exford Road) and across Strathtulloh property to Toolern Creek, then south to the Werribee River crossing at Exford. From here it went along Exford Road to rejoin the main road at Ballan.
This section of road was once part of the Greigs Road alignment but, following realignment of Greigs Road, is now part of the Meskos Road reserve.
The site is of archaeological significance because it forms one of the few remaining cobbled roads in the Shire of Melton and has the potential to provide information about the road construction techniques of mid-19th century rural Victoria. It contrasts with the adjacent delisted section of road, which appears to have been coated with bitumen.
The site consists of a representative sample of the most intact section of a former alignment of Greigs Road. This section of road is 120m long and 4m wide, although the cartilage of the listing is 20.5m wide to match the width of the delisted section. The track includes a slightly raised embankment, approximately 0.2m above the surrounding floodplain, cobbled road surface and road edging.
