Click on any King's Highway route marker sign from the menu below to see a detailed history and a link to a route map of that highway, showing historical re-routings
and realignments. Most of the route maps are still under development and will be posted later. For all other Ontario Highways, please return to the
Main Highway List. Enjoy!
