It is a major connector between most of the major radial routes emanating from central Sydney, and a major link between the northern and southern parts of the Sydney tolled orbital freeway. It is the most direct, although not necessarily the quickest, route across Sydney between the South Coast and the North Coast. It is one of only three road connections between the Northern Beaches region of Sydney and the rest of Sydney (the other two being route A38 (Warringah Road) and the A8.

Most of the route has been progressively upgraded to three lanes in each direction (although parking is permitted in the kerbside lanes in some sections). Sections which are only two lanes in each direction remain, between Beverley Hills and South Hurstville, along Homebush Bay Drive, and between St Ives and Terry Hills. Between Mona Vale and Terry Hills, most of the eastern section of Mona Vale Road is only 1 lane in each direction. Much of the route becomes very congested in peak hour.

The name "A3" is the route allocation for the route as a whole, not a road name. The A3 route runs along a whole series of differently named roads. From north to south they are:

• Mona Vale Road
• Ryde Road
• Lane Cove Road
• Devlin Street
• Church Street
• Concord Road
• Homebush Bay Drive
• Centenary Drive
• Roberts Road
• Wiley Avenue
• King Georges Road
