Building a tunnel crossing the Han river is deemed a crucial project to Danang’s development over the rest of the decade, as the future tunnel would contribute to mitigating the traffic volume at three existing bridges that connect to Hai Chau and Son Tra districts.

The project is embedded in the revised general construction planning of Danang to 2030, and Danang’s underground urban space construction planning to 2030.

In light of the draft planning, this underground tunnel project is one of the infrastructure projects in Danang’s downtown areas, along with several other projects like building Le Duan road to connect existing Dong Da road, and building a flyover to connect Road 29/3 with Bui Ta Han road.

The future tunnel crossing the Han river would be about one kilometre long, starting at the intersection between Dong Da and Tran Phu roads in Hai Chau district, in which Dong Da road directly links to Danang railway station, and connects to Danang International Airport.

The project’s ending point is the intersection between Van Don and Tran Hung Dao roads, in which Van Don road directly links to the National Highway No.14B and Tien Sa Port.

The tunnel project is expected to be a highlight for Danang’s urban landscape. According to the draft planning, Danang aims to expand the existing passenger terminal and build a new one for Danang International Airport.

Over the next decade, the city envisages building a new terminal for local passengers in the airport’s southeast, combined with the existing T2 terminal for international passengers and expanded T1 terminal for local passengers to constitute a mega terminal complex capable of welcoming 15 million passengers a year.

The airport’s capacity-building project during the period will require about $370 million in total investment value.

Also, according to the draft planning, Danang also aims to renovate and build a new freight terminal reaching capacity of 100,000 tonnes per year in the airport’s east, and build a new freight terminal with capacity reaching 100,000 tonnes a year combined with a logistics centre west of the airport. The total investment value to raise the airport’s capacity is estimated at $826 million.
