History of Secondary Highway 634 (#1):

The first highway route in Ontario known as Secondary Highway 634 was a collector highway in the District of Sudbury which once extended from Highway 144 near Chelmsford to Highway 69 at Val Caron. The history of Highway 634 dates back to the early 1960s, when the Department of Highways of Ontario (DHO) assumed jurisdiction over the Chelmsford-Val Caron Road via Blezard Valley as a new provincial highway. A Preliminary Assumption Plan was prepared in July 1961, which showed the proposed route of a new Secondary Highway northwest of Sudbury. The new route began at Highway 544 (now known as Highway 144) east of Chelmsford and ended at Highway 69 in Val Caron. This plan was registered on July 27, 1961 and the new highway was formally designated as Secondary Highway 634 by an Order-in-Council, effective July 20, 1961. The new highway was just under 12 miles (19 km) in length and was shown as a paved highway on the 1962 Official Ontario Road Map. However, other DHO records suggest that the last mile of Highway 634 from Main Street (Chelmsford) to the Highway 144 Junction wasn't paved until 1966.

Apart from some minor road realignments, the route of Highway 634 remained more or less unchanged until the 1970s. Once the Regional Municipality of Sudbury was created in the 1970s, road administration was reviewed throughout this area. During 1974, jurisdiction over the entire route of Highway 634 was transferred from the province to the newly-created Regional Municipality of Sudbury. The majority of the highway was transferred on May 1, 1974. However, a short section of Highway 634 from First Avenue (now known as Menard Street) westerly for 0.39 miles through the built-up section of Blezard Valley was briefly retained in the provincial highway system until November 13, 1974, when it too was transferred. This section of the highway was still under construction through Blezard Valley during the Spring of 1974, so it was retained under provincial jurisdiction until the project was completed. Former Highway 634 is now known as Sudbury Road 15. While the first route of Highway 634 in the Sudbury area ceased to exist in 1974, the Highway 634 designation was used again on a different highway in the Cochrane area in the 1970s. The route of Tertiary Highway 807 from Smooth Rock Falls to Fraserdale was re-designated as Highway 634 in 1976.
