History of Secondary Highway 641:
Secondary Highway 641 is a local highway in the District of Kenora, which serves as a connecting highway between Highway 596 and Highway 17 northwest of Kenora and Keewatin. Highway 641 was created out of a route renumbering in 1964, when a section of Highway 596A lying between the Highway 17 Junction west of Kenora and the Highway 596 Junction at Pellatt was renumbered as Highway 641. For many years, Highway 641 was gravel-surfaced. The first 2 km of Highway 641 was paved in 1982, as part of the Kenora Bypass (Highway 17A) construction. The balance of the highway was paved in 1985. Unless posted otherwise, the speed limit on Highway 641 is 80 km/h (50 mph). There are no services available on this highway.
