History of Secondary Highway 634 (#2):
The second Highway 634 came into being after a route renumbering in 1977. That year, the entire length of Highway 807 was renumbered as Highway 634. This highway starts at the Highway 11 junction in Smooth Rock Falls and heads north to the massive hydro-electric dam at Abitibi Canyon. The 2003 Ontario Official Road Map erroneously indicates that this road is still entirely paved. In fact, the northernmost 15 km of this highway is now gravel surfaced. A different, unrelated Highway 634 existed in the Sudbury area in the 1960s and early 1970s.
Warning: There are no gas stations on Highway 634.
