M23 is a major north-south route within the ACT.

The M23 section acts as a bypass of the urban area of North Canberra and travels past Canberra International Airport.

The route from Ginns Gap to Gilmore is divided motorway and arterial road standard, with at least 2 lanes in each direction and all junctions between Majura and Symonston grade separated. From Gilmore to Williamsdale, the route in undivided rural highway standard with occasional overtaking lanes.

Traffic types vary considerably along the route.

M23 crosses the Molonglo River at Pialligo, which feeds Lake Burley Griffin.
