History of King's Highway 11B (Orillia):
The Orillia Highway 11B Business Route was created in 1959, shortly after the Orillia Bypass was opened to traffic. For a few years following the
completion of the Orillia Bypass in 1954, the old route of Highway 11 through downtown retained its original designation. However, in 1959, the old
alignment through downtown (via Memorial Avenue, Colborne Street, Front Street and Laclie Street) was redesignated as Highway 11B. In 1960, the highway was
rerouted along Coldwater Road and West Street instead of along Front Street. Some maps show Highway 11B turning onto Barrie Road from Memorial Avenue, and
then following King Street through to Front Street and Laclie Street. The route was 8.7 km in length. The Highway 11B Business Route lasted until 1982,
when it was redesignated as a secret, unposted 7000-series highway number (Highway 7183). The route of Highway 7183 was modified slightly in the 1980s,
essentially restoring the pre-1960 route of Highway 11B via Front Street. Highway 7183 lasted until March 31, 1997, when it was turned over
to the County of Simcoe and the City of Orillia. The route within Simcoe County is now known as Simcoe Road 49. The sections of former Highway 7183 within
Orillia are now known by their municipal street names only.
