General Information:

M2 / A2 is a major route located in the Sydney area, linking the northwestern suburbs with Sydney's inner suburbs, and eventually via, several other routes to the central business district.

The standard of the route varies from multi-laned arterial road through to freeway standard (covered by the 21 km long Hills Mwy) ². It passes through inner city suburbs, residential areas, light industrial areas and semi-rural areas.

The Hills Motorway segment of M2 was funded and built by the private sector which will operate, maintain and repair the motorway until 2042, when it will revert to the ownership of the NSW government. The Hills Motorway consists of a four-lane motorway plus a two-lane busway (between the east-bound and west-bound carriageways) from Beecroft Road to Old Windsor Road, breakdown lanes and cyclist lanes. ²

Old Windsor Road and Windsor Road:

1792 onwards: Construction of what is now named Windsor Road and Old Windsor Road. ²

1794: A road was established between the Green Hills / Hawkesbury area and the older settlement at Parramatta. ²

1797: Governor Hunter ordered landholders to undertake road improvements along the Hawkesbury Road, including widening the road to 20 feet. (This is the date for the creation of the Windsor Road as a carriageway). ²

1802: A bridge was constructed at a new South Creek crossing of the Windsor Road, financed by tolls, and replacing the previous punt crossing further east. The current road alignment at South Creek dates from this time. The earlier road alignment, leading to the punt crossing, is reflected in the alignment of the present day Hawkesbury Road. ²

1805: Surveyor James Meehan surveyed an alignment between Parramatta and Kellyville which became the basis for the (New) Windsor Road in 1813. ²

1810: Governor Macquarie established five towns along the Hawkesbury River: Windsor, Richmond, Pitt Town, Wilberforce, and Castlereagh. A contractor, James Harrex, was engaged to build a new turnpike road between Parramatta and Kellyville, following Meehan's 1805 alignment via Castle Hill. This new alignment would avoid the hilly section (referred to by Governor King in 1803 as "the Seven Hills") of the original (Old) Windsor Road. The new alignment also enabled a more direct route to the Hawkesbury from Sydney. ²

1812: Upon the failure of James Harrex to complete the new road works, John Howe took over and completed the contract, which included the construction of 70 bridges. The new road was 32 feet wide and alignment stones marked the carriageway. ²

1810s: Governor Macquarie introduced a toll system on the Windsor Road with toll gates north of Parramatta and south of Rouse Hill. ²

1816: Construction of a toll house at Rouse Hill. ²

11 September 1833: Windsor Road was proclaimed as a Main Road and gazetted, with Old Windsor Road being declared a Parish Road. ²

1835: A toll house, the second on the site, was constructed at the South Creek crossing near Windsor. ²

1849: The Windsor Road Trust was formed to oversee maintenance of the Windsor Road. ²

1853: Fitzroy Bridge constructed across South Creek at Windsor, replacing the earlier Howe's Bridge. ²

1924: The Department of Public Works used water-based macadam in reconstructing the Windsor Road near Rouse Hill. Water-based macadam was an improved road surface treatment necessitated by the rapid rise of the motor vehicle. ²

1926: A bitumen coating was laid completed on Windsor Road near Rouse Hill, and renewed in 1928-9. ²

22 May 1928: Windsor Road, together with Bells Line of Road and the Darling Causeway was announced as Main Road 184. ²

1940s: Cutting and filling of the Old Windsor and Windsor Roads was reportedly undertaken by the United States military to prepare evacuation routes should a Japanese invasion take place in Sydney. ²
