After 32 months of construction, the drilling and tunnelling work at the Hai Van Tunnel 2 project has been already completed. The Hai Van Tunnel 2 which is considered as the longest road tunnel in Southeast Asia is expected to open to traffic in 2020.

The over 7,200 billion VND Hai Van Tunnel expansion project was approved by the Ministry of Transport in 2016. Accordingly, the 1st stage of the project focused on upgrading the existing main Hai Van Tunnel and a section of the National Highway 1A. Work started on the stage in April 2016 and finished in August 2017.

Starting on 25 February 2017, the 2nd stage of the project involves expanding the over 6.2 km-long emergency tunnel, which lies parallel to the existing main tunnel, into a 2-lane tunnel, and building a new 2.1 km-long stretch of road to Thua Thien-Hue Province’s Lang Co Town, and a 4.3 km-long roadway leading to Da Nang. The construction cost of the 2nd stage is expected to be 8,516 billion VND.

The construction of this project was facing some obstacles relating to site clearance work and financial shortage. However, the construction units have gradually removed obstacles, so the drilling work at the Hai Van Tunnel 2 project has been completed 6 months ahead of schedule.

Thanks to the great efforts made by relevant agencies, the progress of the project has been kept on track.

After 32 months of construction, the drilling and tunnelling work at the Hai Van Tunnel 2 project has been already completed.

The 2nd stage of the project features the construction of a new 2.1 km-long stretch of road to Thua Thien-Hue Province’s Lang Co Town, and a 4.3 km-long roadway leading to Da Nang in Lien Chieu District's Hoa Hiep Bac Ward. The Hai Van Tunnel 2 is 6.2 km in length and 9.75 m in width.

Currently, the tunnelling and cleaning work at the project has been already completed.

The completion of the Hai Van Tunnel 2 project will help shorten travel time for vehicles on the North-South road from 2020.
