Geology/History lesson
Seven Canyon Tunnels
The TransCanada highway from Hope to Boston Bar passes through seven highway tunnels blasted through the canyon rock. The first is the Yale Tunnel, 286 metres long, just 1.5 km east of Yale followed by the 146 metre long Saddle Rock Tunnel (named for the saddle shaped rock in the Fraser River), with the 292 metre Sailor Bar tunnel next. After passing through Spuzzum and Alexandra Bridge Provincial Park, you pass through the 290 metre the Alexandra Tunnel, and just west of Hells Gate Airtram are the Hell's Gate and Ferrabee Tunnels, each approximately 100 metres long. The last of the seven tunnels is the 610 metre China Bar Tunnel, named after the gold-bearing sand bar in the Fraser River that was re-worked by the Chinese (who became very rich), after it was abandoned by white prospectors.
