Second KVR Tunnel

Second KVR tunnel in Myra Canyon

This tunnel in Myra Canyon, Anderson’s tunnel, holds a wartime secret. The year stamped above the entrance — 1941 — hints at its role.

During WWII, rail lines were vital, and the Canadian Pacific Railway, the parent company of the KVR, shored up this tunnel against weak rock and possible sabotage by enemy sympathizers.

Beyond ordinary freight, it carried materials for a top-secret Allied undertaking: the Manhattan Project. Heavy water from Cominco in Trail, along with lead and zinc for British ammunition, passed through here, making this quiet tunnel a crucial artery in the war effort.
