Northern Expressway

The Northern Expressway (route M2) (formerly route M20), also known as the Fatchen Northern Expressway, is a 23 kilometre long controlled-access highway in Adelaide, South Australia.

It travels from Gawler (on National Highway A20, the Sturt Highway) to Port Wakefield Road (on National Highway A1).

The road has been built to four-lane standard and provides a faster route between Adelaide and Gawler, whilst reducing the amount of traffic on Main North Road, which passes through the heart of the northern suburbs and is interspersed with frequent traffic lights.

It also allows freight vehicles to avoid residential areas and go straight to Port Wakefield Road and onto the Port River Expressway (A9) to reach the harbour at Port Adelaide.

Cycling is not permitted on the Expressway.

The Stuart O'Grady Bikeway is a sealed shared cycling and walking path adjacent to the eastern side of the expressway.

The northern end connects to the on-ramp from Two Wells Road to the Gawler Bypass Road, and the southern end is adjacent to Port Wakefield Road at Mill Road.
