History of King's Highway 133 (#2):
The second highway route in Ontario that was designated as King's Highway 133 was a minor collector highway which connected Highway 33 in Millhaven to
Highway 401 near Odessa. The highway was first commissioned on March 10, 1965, at a total length of 10 km. The highway remained in the King's Highway
network until March 31, 1997, when it was downloaded in its entirety to the County of Lennox and Addington. Since 1997, the road has been known as Lennox
and Addington County Road 4. A different, unrelated Highway 133 existed near Peterborough between 1956 and 1960.
