History of Secondary Highway 630:
Secondary Highway 630 is a local highway in the District of Nipissing which connects the former sawmill community of Kiosk located southwest of Mattawa to Highway 17.
The history of Highway 630 dates back to the early 1960s, when the Department of Highways of Ontario (DHO) assumed jurisdiction over the Kiosk Road. A Preliminary
Assumption Plan was prepared in July 1961, which showed a new Secondary Highway which extended southerly from Highway 17 into Algonquin Provincial Park to Kiosk. This
plan was registered on July 28, 1961 and the new highway was formally designated as Secondary Highway 630 by an Order-in-Council, effective July 20, 1961. The new
highway was approximately 19 miles (30 km) in length. Highway 630 was initially gravel-surfaced at the time of assumption. A bituminous surface treatment was applied
to the first 3 1/2 miles of the highway from Highway 17 southerly in 1961. An additional 6 miles of mulch pavement was laid from that point southerly towards Kiosk,
with 4 miles completed in 1962 and two miles completed in 1963. A mulch pavement surface was laid along Highway 630 in the vicinity of Kiosk for a distance of 1 1/2
miles in 1964 and an additional 3 miles laid in 1965. A final section of mulch pavement was laid in 1967, which completed the paving work along Highway 630 between
Kiosk and Highway 17. The Official Ontario Road Map for 1967 indicates Highway 630 with a fully paved surface.
Apart from some minor realignments in a few locations, the route of Highway 630 has remained more or less unchanged since the 1960s. Although the route of Highway 630
remains in Ontario's provincial highway system to this day, it no longer services the community of Kiosk. After a devastating fire tore through the Kiosk Sawmill in
1973, Kiosk's residents slowly vacated the community. Kiosk subsequently became a ghost town. However, Algonquin Provincial Park's Kiosk Campground is still in
operation today and is now the only major feature remaining at Highway 630's southern terminus. Highway 630 is the only other Ontario Provincial Highway to enter
Algonquin Provincial Park, aside from the much more famous Highway 60 Corridor between Dwight and Whitney. Unless posted otherwise, the speed limit on Highway 630 is
80 km/h. There are no services available on this highway.
