500 series: Flamborough

[Hamilton, ON highway map]

The Town of Flamborough was formed through the 1974 administrative consolidation of three historical townships (Beverly, West Flamborough, and East Flamborough), less the portions that had been annexed by Halton County (Burlington) and the Waterloo Region (Cambridge) in the sixteen years before.

At the time this highway was added to the regional road system, it consisted of two segments separated by a 2-km jog along RR 97. It's unclear whether the "552" designation applied to both segments (with a discontinuity or concurrency in between), or to the south segment only.
