This was named after W.G (Bill) Auld MBE, a local resident who was a staunch advocate for the motorway bypassing Fairfield. He died shortly before the completion of the motorway but on the day of his funeral his hearse took him down the route he fought hard to implement.) There is another half-diamond interchange (northbound off, southbound on) and a separate overbridge for Morris Road.

workings that created major difficulties in the stabilisation of the land along the route. The Saddle Hill section was upgraded at this time to a four-lane divided motorway to take advantage of the preparatory earthworks completed in the 1960s. The completion of the
Fairfield section meant that SH 1 was now an uninterrupted four-lane divided motorway from Lookout Point to the SH 87 interchange.
491:. Earthworks were undertaken to allow for the construction of a four-lane motorway with northbound and southbound slip lanes extending from a future interchange with SH 87 at Mosgiel. At the time the road was constructed with two lanes and a northbound passing lane northward from the SH 1/SH 87 intersection.
