The Barossa Valley Way is the main road linking most of the major towns of the Barossa Valley in South Australia. It is designated as highway B19. It is 34 km long, roughly following the North Para River from the Sturt Highway at Nuriootpa through Tanunda, Rowland Flat and Lyndoch to Gawler, where it again meets the Sturt Highway (almost - the Barossa Valley Way approaches from the East and terminates in the main street, but the Sturt Highway bypasses the town to the West). Route B19 continues through Gawler on the Adelaide Road to the interchange at the southern end of the Gawler bypass road.
