History of King's Highway 22A:
The actual existence of King's Highway 22A has not yet been confirmed. Some road maps from the 1950s identify a Highway 22A, which ran from Watford to Hickory Corners, via Strathroy. This highway supposedly followed the original route of Highway 22 that existed up until the late 1940s. This section of Highway 22 was relocated onto a new route in 1947 which bypassed Strathroy altogether. The old alignment of Highway 22 was transferred to Middlesex and Lambton Counties in 1947, so it is not clear whether or not this route did indeed exist, or whether the presence of this route on contemporary road maps was simply a cartographic error. If anyone can provide me with any additional information about Highway 22A, it would be greatly appreciated.
