General Information:

National Route 32 is the main route linking the New South Wales state capital, Sydney, with the west of the state. The road varies from arterial road conditions, rural expressway and rural highway.

• Great Western Highway:

The highway is signposted as National Route 32 from Glenbrook in Sydney's west, to its terminus at Bathurst. Great Western Hwy is signposted as SR44 in the sydney area.

The Great Western Highway is regarded as one of the oldest roads in Australia. Starting as George Street in the Sydney CBD, and following Parramatta Road, it heads west across metropolitan Sydney to Penrith, where it crosses the Nepean River. It then crosses the Blue Mountains and the Great Dividing Range to Bathurst.

The road across the Blue Mountains was built by William Cox in the 1800s shortly after a viable route across the mountains was discovered. An obelisk at Macquarie Place in Sydney records the construction of the road during the rule of Governor Lachlan Macquarie.

In the 90s, the highway was terminated at Emu Plains with the closure of the Knapsack Gully Viaduct. An extension to the Western Mwy (Metroad 4) at Emu Plains was constructed, which rejoined with the highway at Glenbrook. The upper portion of the Great Western Highway from Russell Street is now only used by residents and cars coming from Blaxland via Mitchells Pass. Mitchells Pass is section of the former main road over the Blue Mountains.
