History of Secondary Highway 662:
Secondary Highway 662 was a minor collector highway that served as an access road through Nairn Centre, west of Sudbury. The history of this route is somewhat of a mystery. A highway designation plan was filed on September 16, 1970, which indicated that Smith Street and McIntyre Street were both acquired by the Department of Highways as a new provincial highway. The plan indicates that this new road was designated as Secondary Highway 662. At some point after the route was designated in 1970, the route number was changed from Highway 662 to an unposted 7000-series highway designation (Highway 7082). However, the route of Highway 7082 also included a substantial portion of the former alignment of Highway 17 between Nairn Centre and Whitefish. It is not certain at this time whether Highway 662 was ever actually a posted route number along the highway. Given the extremely short length of the highway and the fact that it only intersected with an unposted 7000-series highway at its northern terminus, it seems doubtful that the Highway 662 route number was ever posted along the highway. It should also be noted that Highway 662 never appeared on the Official Ontario Road Map. Today, the former route of Highway 662 is paved with a posted speed limit of 50 km/h (30 mph). There are no services on this highway, although there are services located along Highway 17 through Nairn Centre.
