SUBSEA CELEBRATION
This article describes a breakthrough on the Hitra Froya road tunnel project off the north coast of Trondheim, Norway. A 3-lane, 5.65 km-long subsea tunnel between the mainland and the island of Hitra was completed in 1994. The breakthrough involves the second tunnel, between Hitra and the neighboring island of Froya, that is 1 year ahead of schedule and will link the 2 islands and provide an all-weather route from Froya to the mainland. The 5.3 km-long crossing is being developed from both the Hitra and Froya portals and 3.6 km of the tunnel is under the sea. It will have a 2-lane road with a cross-section of 55 m squared. Progress in another tunnel project, the A71 highway in Germany connecting Erfurt with Schweinfurt, is also described. Atlas Copco Rocket Boomers are being used in both projects.
