Denmark is set to begin work on an undersea road and rail tunnel across the Fehmarn Belt strait to Germany. The project is slated for completion in 2020.<br /><br />Nine identical reinforced concrete segments will be joined to form a single tunnel section. The tunnel will consist of of 89 such sections. <br /><br />Finished tunnel elements will be moved to a dry dock which will then be flooded with seawater. Tug boats will be used to move the floating tunnel sections towards pre-dug seabed trenches.<br /><br />Pontoons will then be attached and the elements lowered to the seabed, 40 meters beneath the surface.<br /><br />The 18 km-long undersea tunnel will be the world's longest tunnel of its kind as well as the longest combined rail and road tunnel.<br /><br />FOR MORE NEXT MEDIA ANIMATION, GO TO: http://www.youtube.com/subscription_center?add_user=NMAWorldEdition <br /><br />FOR MORE NEXT MEDIA ANIMATION IN ENGLISH, GO TO: http://www.youtube.com/subscription_center?add_user=NMAtv <br /><br />FOR MORE TOMONEWS US, GO TO:<br />http://www.youtube.com/subscription_center?add_user=TomoNewsUS <br /><br />FOR MORE TOMONEWS JP, GO TO: http://www.youtube.com/subscription_center?add_user=TomoNewsJP <br /><br />FOR MORE APPLE DAILY ENGLISH, GO TO: http://www.youtube.com/subscription_center?add_user=AppleDailyEnglish <br /><br />CHECK OUT THE ODDBODS!<br />http://www.youtube.com/user/nxTomo
