Tunnellen omfatter fortsat kun et smalt envejsrør (7 m bredt) med bitumenbelægning, og altså brændbar belægning, uden central bjærgningsskakt og uden parallel evakueringsgang.
The tunnel is still a narrow (seven metres wide) single-direction tube that has no tarmac-covered and, therefore, fire-resistant surface, central escape hatch or parallel evacuation tunnel.
