General Information:
Alternate National Route 1 was a collection of separate roads in different parts of South Australia that paralleled National Route 1 or offered a different route to the same destinations, but in the case of Murray Bridge to Callington, the route is the former NR1 routing. The route of ALT-NR1 between Kingston SE and Millicent is the pre-1933 Princes Hwy routing. All of the ALT-NR1 routes in South Australia are rural highway standard, generally with 2 lanes in each direction, mostly servicing tourist areas and passing through mostly residential, rural and commercial zones.
