The Fraser Canyon offers low-elevation access to the British Columbia interior, and was the favored route successively for the Cariboo Wagon Road (1860s), the Canadian Pacific (1880s), the Canadian National (1900s), and eventually the Trans Canada Highway (1960s).
Automobile traffic typically prefers the more direct route offered by Highway 5, except as on this trip, when winter driving conditions on Coquihalla Pass (1244m) were hazardous.
