Ontario Highway 70 (#2) History - The King's Highways of Ontario

The second King's Highway 70 served as an alternate route to Highway 6 between Owen Sound and Hepworth. This short but important trunk highway was only 15 km in length, but it carried most of the traffic heading to and from the Bruce Peninsula. The highway was first commissioned in 1965, when the existing county road through Shallow Lake was designated as Highway 70. The highway was completely paved prior to being assumed as a King's Highway. On January 1, 1998, Highway 6 was downloaded between Hepworth and the Highway 21 Junction at Alvanley. In an effort to improve route numbering logic, and to reunite the discontinuous north and south sections of Highway 6 created by the 1998 highway downloading, the Ministry of Transportation chose to renumber Highway 70 as Highway 6. As a result, Highway 70 ceased to exist. Please visit the Highway 70 Mileage Chart page for a list of mileage reference points along Highway 70. A different Highway 70 existed near Kenora between 1937 and 1959, but this former route had no relation to the Highway 70 that existed near Owen Sound between 1965 and 1998.
