All Routes under 100 were renumbered in the 1970s. Some are now Routes in the 100-range; others became Autoroutes. Autoroutes are numbered under 100 and above 400, and the conflicting range was changed.[1][2][3]
History
Prior to the early the 1970s, Quebec's provincial routes were numbered from 1-108. With the development and subsequent expansion of the
Autoroute system, as well as an effort to simplify route connections and reduce motorist confusion.[4] First proposed in 1966 with the intent of being implemented for
Expo 67,[4] the changes did not occur until the early 1970s. As part of the renumbering, the present blue Autoroute and green Provincial highway shields were introduced.
