History of King's Highway 4B:
King's Highway 4B was a short business route connecting Downtown St. Thomas to Highway 4. The St. Thomas Business Route started at Highway 4 and followed Wilson Avenue and Elgin Street to Highway 3 (Talbot Street). It is believed that Highway 4B was actually a municipally-signed business route, since Ministry of Transportation mileage tables have never listed this highway as an official route. It is also not certain how many years Highway 4B was in existence. It seems that the route was created sometime during the 1960s and remained as a posted route up until the 1970s.
