“The Fraser Canyon Highway Tunnels were constructed in the late 1950’s to about the mid 1960’s as part of the Trans Canada project. There are seven tunnels in total, the shortest being 57 m (190 ft); the longest, is 610 meters (2,000 ft) and is one of North America’s longest. They are situated between Yale and Boston Bar. In order from south to north, they are: Yale, Saddle Rock, Sailor Bar, Alexandra, Hell’s Gate, Freebee and China Bar. The Hell’s Gate tunnel is the only tunnel that does not have lights, while the China Bar tunnel is the only tunnel that requires ventilation. A recent project on some of the Fraser Canyon Tunnels has been to install warning lights that are activated by cyclists before they enter the tunnel. This was required because the tunnel is curved.
