Abstract

Two tunnel boring machines (TBMs) are reported to be facing each other along Denmark's Great Belt waterway as part of a much-delayed $3.3 billion tunnel link between cities. Similar work on a second tunnel is expected to continue since the two TBMs are still about 165 meters apart. The 7.4-km. tunnels are part of the Zealand-Funen fixed link which is expected to carry trains and road vehicles along a 17.5 km. stretch.
