The Lincoln Highway passes directly through Whyalla. The city is served by a coach bus service operated by Stateliner which operates four services to and from Adelaide (via Port Augusta) each week day (less on weekends) and one service each way to Port Lincoln. There are however occasional exceptions to the week day route due to lack of demand to travel through Whyalla.
