Abstract

The Airside Road Tunnel (ART) at Heathrow airport will provide all- weather ground vehicle access from the Central Terminal to western aircraft stands. Being done in the shadow of the 1994 tunnel collapse at the Heathrow express Tunnel (HEX) project, it is being carried out with extensive attention paid to safety. It is being constructed with a tunnel-boring machine starting eastbound. The tunnel will be 1.3 km long, 8.1 m. in diameter, and have 2 bores. Surface settlement on the active airport surface above will be limited to 30-40 mm, which will be monitored with extensive instrumentation. Completion of the tunnel is expected by February 2005.
