The subway tunnel is a newly built 90m long pedestrian tunnel at King’s Cross. The beautifully designed tunnel links the two arterial transport hubs – St Pancras International and King’s Cross Underground stations – to the new public spaces, restaurants, offices and homes at King’s Cross. The gently curving underground tunnel features an ‘art wall’ made from LED lights, which will be used to showcase artistic commissions. The art light wall was designed by Spiers & Major and built by The Light Lab. Running the length of the tunnel the light wall contains 190 controllable vertical pixels set behind 12mm toughened glass.
