The road was a toll-route and built by private contractor Gustavus Blin-Wright, a prominent British-Swedish entrepreneur in colonial British Columbia who also contracted to build roads and provide steamer services in the Kootenay region.
Blin-Wright also operated the steamer which connected the end of the road at Alexandria with Quesnel (then Quesnellemouthe).
Cattle drives were common along this trail to supply the gold miners, who arrived in British Columbia in the late 1850s.
From there it turned north and crossed the Waterville Plateau to reach the Columbia River near Fort Okanogan.
The Old Cariboo Road started at Lillooet (or 0 Mile House) where it directly went to Alexandria.
