In the event of a near miss nuclear bomb blast, the pressure wave would blow through either the main entrance or the second entrance and straight through the tunnel and out the other side. This was to prevent the blast from directly hitting the steel entrance doors to the Diefenbunker in a passage 90 degrees from the main tunnel.
