This is a list of secondary highways in Sudbury District, most of which serve as logging roads or provide access to provincial parks and isolated areas in the Sudbury District of northeastern Ontario.

Its only purpose is to connect the Highway 17, the Trans Canada Highway, in the community of Massey (township of Sables-Spanish Rivers) to logging areas and provincial parks north of the community.

The route connects Highway 607 to Bon Air and French River Provincial Park.

The northern terminus of the highway is Highway 607, while the southern terminus is in French River Provincial Park, 0.5 kilometres past Bon Air.

That route travelled south to Westree along the alignment of what is now Highway 144, which was under construction at the time.
