 SH1 traverses Dunedin as two multiple-lane one-way streets, travelling past the University of Otago and the CBD before rejoining as a single multiple-lane road at the Andersons Bay intersection; a busy signal-controlled "T" intersection with SH1 and Andersons Bay Road in South Dunedin.From the intersection SH1 becomes a four lane median-divided road through to the Barnes Dr intersection, crossing King Edward Street (South Dunedin's main street) on twin over-bridges at Kensington, and twin over-bridges near the Glen, crossing South Road just north of Carisbrook.While this section meets most technical definitions of a motorway with full limited access including no pedestrian or cycle traffic, it is not designated a motorway by the NZ Transport Agency due to its short length.
