Windsor Road: A History of New South Wales Infrastructure
Windsor Road stands as a vital artery in the transport network of New South Wales, reflecting over two centuries of urban growth and legislative evolution. From its origins as a colonial path to its current status as a modern alphanumeric route, the road's development mirrors the broader expansion of the region's infrastructure.
The Early Alignments and Evolution
The story of Windsor Road began in 1794 with the opening of the original route connecting Windsor and Northmead. As the colony grew, the need for more efficient travel led to the opening of a newer alignment in 1812. This new path branched off from the original route at Kellyville and terminated in North Parramatta.
This change created a distinction between the two paths: the original section between Kellyville and Northmead was renamed Old Windsor Road. For nearly two centuries, these two roads met at a T-junction. It was not until 2002 that the junction was reconstructed, restoring the importance of Old Windsor Road and allowing through traffic to flow seamlessly along the original alignment once again.

Legislative Framework and Classifications
The formal management of the road shifted with the passing of the Main Roads Act of 1924. This legislation allowed the New South Wales Parliament to declare "Main Roads," which received partial funding from the State government via the Main Roads Board (the precursor to Transport for NSW).
On August 8, 1928, the route was officially declared as Main Road No. 184. This designation spanned from the intersection of Pennant Hills Road, just north of Parramatta, to Windsor, continuing westward through Richmond, Bilpin, and Bell until it met the Great Western Highway at Mount Victoria. Following the Main Roads (Amendment) Act of 1929, this was slightly amended to Main Road 184 on April 8, 1929.
Later, the Roads Act of 1993 updated how roads were classified and declared across the state. Under this updated legal framework, Windsor Road maintained its status as part of Main Road 184.
Route Numbering and Modern Transitions
Throughout the late 20th and early 21st centuries, Windsor Road underwent several numbering changes to help motorists navigate the growing network:
- 1974: The road was allocated State Route 40.
- 1993: Metroad 2 was assigned to the section between Windsor and Showgrounds Road in Castle Hill.
- 1997: With the opening of the M2 Hills Motorway, Metroad 2 was truncated to the intersection with Old Windsor Road in Kellyville.
- 2007: State Route 40 was realigned to follow Metroad 2 along Old Windsor Road, leaving the southern portion of the road unallocated.
- 2013: New South Wales transitioned to an alphanumeric system. Consequently, State Route 40 was abolished, and Metroad 2 was replaced by route A2.
