The two metro lines that will connect downtown areas are among 57 major infrastructure projects that city authorities are calling for investment for the 2020-2025 period.

The city envisages both routes being built under the public-private partnership (PPP) investment form.

The east-west route would run from Nam O 1 residential area in Lien Chieu District through downtown areas to My Khe Beach in Son Tra District, while the south-north route will connect the Son Tra Tinh Vien nature reserve on Son Tra Peninsula, areas around the Da Nang Airport and the Khue Trung area in Cam Le District.

The city also called for investors to build an electric metro train project connecting with the neighboring Hoi An Town, a famous tourist hotspot in Quang Nam Province. This project carries an estimated value of VND7.49 trillion to VND14.99 trillion.

Another project is a 3.7-kilometer tunnel at the Da Nang Airport with six lanes that requires a total investment of VND8.2 trillion. The project's investment will be raised from the city's budget, official development assistance (ODA) and the PPP model.

The city of 1.1 million also seeks investment for the Lien Chieu Port, which is expected to use VND3.4 trillion from the state budget and VND3.9 trillion from the private sector.

The 220-hectare port, expected to spearhead Da Nang’s logistics development, will be built below Hai Van Pass in central Vietnam.

City authorities are also seeking investors for other major projects like the 500-bed international standard oncology treatment center at VND11 trillion, the VND5-trillion Opera House, a VND3 trillion waste treatment plant worth up to VND3 trillion and VND4.5 trillion horse racing.

Da Nang, the urban hub of central Vietnam and a popular tourism hotspot, is considered the country's third most important city after Hanoi and Ho Chi Minh City.
