Route Overview:

National 23 is a north-south route through the south-eastern part of NSW. It provides a conveniant alternate route to Sydney from the East Gippsland area of Victoria, as well as access between Sydney and Canberra which are agruably Australia's tow most important cities.

National 23 is broken into 3 parts, the Federal Hwy in NSW, the arterial roads it utilises through Canberra and the Monaro Hwy south of Canberra. The route currently terminates at the NSW/VIC border north of Cann River, formerly extending south into Victoria to meet the Princes Hwy at Cann River. The Victoria section of this route was re-numbered B23 as part of the Victoria Statewide Rotue Numbering System in 2000-01.

National 23 was signposted on the Federal Hwy in 1956, two years after being designated as NR23. In 1974, this section was proclaimed a National Highway and therefore gained the green and gold shield. In 1962, NR23 signage was erected between Canberra and Cooma, later extended to Nimmitabel in 1967. In March 1985 sealing of NR23 within Victoria was completed and NSW finally sealed their last gravel section near the border in August 1999. It was around this time that NR23 was fully signed for the first time, only to be re-badged in Victoria during 2000-01. It was also around 1999 that Victoria re-named their section to match NSW's Monaro Hwy. The Victorian section was previously known as Cann Valley Hwy.
