Hầm Hải Vân - Kỳ Tích Việt Nam Đào Hầm Xuyên Núi 6,2Km

#hamhaivan #hamduongbohaivan #deohaivan I wonder if you have ever driven through Hai Van Tunnel? When you go through, do you feel the same as me? I was both nervous and proud when the wheels went deep into the tunnel, I wondered why they made such a magnificent tunnel? and that is the reason that urged me to come back to learn to make this video to share with you and your friends, because this is such a miracle of our Vietnam in the period of innovation and development, Hai Van Tunnel is not only meaningful in terms of trade connecting the two regions of the South and the North, but it is also an opportunity to open up connections with the world economy, when the traffic infrastructure is completed to attract investment capital from abroad Starting construction from 2000 to 2005, Hai Van Tunnel 1 officially opened to traffic, it was not until 2016 that we started to build the second tunnel and opened to traffic in 2021, so it has been exactly 10 years for this proud century project to be completed to its fullest. Please watch the video to know the reason we built Hai Van Tunnel, how we built Hai Van Tunnel? Who helped us build Hai Van Tunnel? How much does it cost to dig a 6.2km tunnel through the mountain to make Hai Van Tunnel If you find it interesting, please leave a comment to thank those who created the project of the Century for our Vietnamese people! #Hai_Van_Tunnel #Road_Tunnel #Digging_Tunnel_Through_Mountains #Hai_Van_Pass
