A two-inch (50-mm) diameter pilot hole allowed the service tunnel to break through without ceremony on 30 October 1990.

Eurotunnel completed the tunnel on time, and it was officially opened, one year later than originally planned, by Queen Elizabeth II and the French president, François Mitterrand, in a ceremony held in Calais on 6 May
