Former Ontario provincial highway
King's Highway 30, commonly referred to as Highway 30, was a provincially maintained highway in the Canadian province of Ontario. The 51.1-kilometre (31.8 mi)-long route connected Highway 2 in Brighton with Highway 7 in Havelock via Campbellford. Established in 1930, the highway initially travelled only as far north as Campbellford. Alongside the construction of Highway 7 between Peterborough and Perth, Highway 30 was extended north to Havelock in 1934. The route remained generally consistent until 1998, when it was decommissioned and transferred to Northumberland County and Peterborough County. Both counties redesignated their portion of the former highway as County Road 30.
