摘要

Crews working on the Brenner Base Tunnel, the world's longest underground rail tunnel linking Austria and Italy, celebrated the completion of the 16.7-km (10.4-mile) long exploratory tunnel on July 6. The tunnel that connects two Austrian segments forms a continuous 36-km (22.3-mile) tunnel beneath the Alps between Tulfes and Schmirn - around 65 percent of the tunnel's 55 km (34 mile) projected length.
