History of King's Highway 7B (Madoc):
This short-lived Business Route was established in 1967, when a new Highway 7 Bypass was opened just to the north of Madoc. The new Madoc Bypass was completed and officially opened to traffic on September 17, 1967. The old Highway 7 alignment through Downtown Madoc via St. Lawrence Street became Highway 7B. The Business Route was only in existence for about two years. The highway was decommissioned in 1969, when the provincially-owned sections of Highway 7B on the approaches to Madoc were transferred to the Township of Madoc, effective July 1, 1969.
