History of King's Highway 11B (Holland Landing):
The Holland Landing Highway 11B Business Route was created in 1959, when a new four-lane diversion of Highway 11 was completed and opened to traffic. The
new highway bypassed Holland Landing entirely. The old route of Highway 11 through Holland Landing became Highway 11B. The business route was marked on the
Ontario Official Road Maps up until 1971, when the route was apparently decommissioned. Reportedly, Highway 11B continued to be signed as such through
Holland Landing for several years subsequent to 1971. The highway was listed in the Ministry of Transportation's mileage tables as recently as 1977,
although the highway was likely considered to be a connecting link by that point. The route of Highway 11B is now known as York Regional Road 83.
