How did they get the Channel tunnel to meet in the middle?
The service tunnel bores were driven from England and France towards each other. When they were approximately 100m apart a 75mm probe hole was driven to connect the two tunnels. A survey could then be made along the probe hole to dteermine any misalignment between the two tunnels.
Who built the Gotthard tunnel?
AlpTransit Gotthard AG
AlpTransit Gotthard AG was responsible for construction. It is a wholly owned subsidiary of the Swiss Federal Railways (SBB CFF FFS).
