The road tunnel leading to Terminals 2 and 3 is partly closed while safety checks are carried out. The outbound tunnel is closed but the inbound tunnel is open for contraflow movement. There is currently traffic congestion across the Heathrow road network so please avoid travelling by road, and instead use the rail network. Passengers can also use the free rail transfer service from Terminals 4 and 5 to get to Terminals 2 and 3.

We apologise for the inconvenience caused.
