History of King's Highway 11B (Callander):
The Callander Highway 11B Business Route was created in the late 1950s. When the first Callander Bypass was completed and opened to traffic in October
1959, the 3.4 km section of Highway 11 passing through Downtown Callander along Main Street was apparently renumbered as Highway 11B. This route is somewhat
of a mystery, as it never appeared in any of the Department of Highways' mileage logs from the 1960s. In all likelihood, this was an unofficial,
municipally-signed route. The most recent reference to Callander's Highway 11B was in a DHO document dated 1971, which suggests that the route was still
being signed as Highway 11B at that time. The 1977 Official Ontario Road Map was the first edition to show the old Highway 11 route through Callander as a
municipal road, and not as a provincial highway. However, it is not certain if the route was actually decommissioned at that time.
