Ontario Highway 69B History - The King's Highways of Ontario

King's Highway 69B was created when the first Parry Sound Bypass across Mill Lake Narrows was opened to traffic in 1961. The old alignment of Highway 69 through Downtown Parry Sound became Highway 69B. The highway was 4.5 km in length. During the late 1980s, construction began on a relocation of Highway 69 between Mill Lake Narrows and Nobel. Once this new Highway 69 route was completed, the old alignment of Highway 69 via Parry Sound Drive was going to be decommissioned as well. It was determined that the Highway 69B business loop was obsolete, since the highway's northern terminus would be discontinuous once the relocation of Highway 69 was completed in 1992. Accordingly, Highway 69B was decommissioned in 1989.
