List of former Quebec provincial highways

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.

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. First proposed in 1966 with the intent of being implemented for Expo 67, 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.
