Gawler Bypass is a major north–south route in the outer northern suburbs of the city of Adelaide, South Australia, connecting Main North Road to the Sturt Highway, bypassing Gawler. The route was built in 1963 in an attempt to redirect traffic on the national highway out of Gawler town centre. It has been upgraded and realigned several times since then.
