History of King's Highway 11B (Powassan):
The actual existence of Highway 11B through Powassan has not yet been confirmed. The Powassan Bypass opened in 1956, and reportedly, the old alignment of Highway 11 through downtown became Highway 11B for a number of years. The business route apparently lasted until 1967, when it was decommissioned. The old highway is now known as Main Street.
