The northwestern Highway 684 is approximately 57 km (35 mi.) long. It begins near Waseca, at Highway 16, and it ends at Highway 3.

The southeastern Highway 684 is approximately 21 km (13 mi.). It begins at Highway 14 (a.k.a. 22nd Street West) inside Saskatoon (the junction, along with a stretch of Highway 684 extending northward beyond 33rd Street West, was annexed in the early 2000s, and it ends at Highway 305 3 km south of Dalmeny). Long known as Dalmeny Road, in 2012 the section of Highway 684 within Saskatoon's city limits was renamed Neault Road.

The City of Saskatoon and the province plan to ultimately construct an interchange at the junction of Highway 684 and Highway 14 as part of the Blairmore Suburban Centre development and in particular the buildout of the Kensington neighbourhood. Concept maps indicate plans to reroute Highway 684 to link with the Yellowhead highway at a junction with Marquis Road in north Saskatoon.
