The Island Highway is a series of highways that follows much of the eastern coastline of Vancouver Island, British Columbia, Canada.
While the Island Highway has no officially designated starting point, it is understood to begin at the BC Ferries dock in Port Hardy as Highway 19.
At this point, Highway 19A becomes the Island Highway, and runs south through Courtenay, Union Bay, Fanny Bay, and Qualicum Beach until it reaches Parksville (this section of the highway is often referred to as the Oceanside Route).
The highway continues through Ladysmith, Duncan, and several other communities before winding through the higher elevation Malahat district.
Instead and confusingly, "Island Highway" is the name still given to Highway 1A from Goldstream Avenue through Langford and Colwood to Six Mile Road in View Royal, after which the road is briefly named "Old Island Highway" for a few blocks, where the address numbering scheme changes from the 1600s to the 400s, resulting in adjacent businesses have substantially different addresses.
