The proposal to add the two above-mentioned expressways is a notable content in the submission on adjusting the road network planning for the 2021-2030 period, with a vision to 2050, sent by the Vietnam Road Administration to the Ministry of Transport.

Accordingly, the Department of Roads proposed to add a new planning for the Ca Mau - Dat Mui expressway, about 90km long, 4 lanes, with investment progress after 2030.

The reason for adding this expressway is through updating the content of the national master plan on GDP growth rate leading to forecasted increased transportation demand. Ca Mau province has also proactively researched and added this route to the provincial planning.

The Quang Ngai – Kon Tum Expressway is proposed to be supplemented with a new planning with a length of about 136 km, 4 lanes, and an investment process before 2030. The reason is that through updating the contents of the national master plan on GDP growth rate, the forecast of increased transportation demand is forecasted; related localities have also proposed to supplement the planning of this expressway to connect from Quang Ngai to the Central Highlands and connect with Laos at Bo Y border gate.

Another expressway, Noi Bai – Bac Ninh – Ha Long, is also proposed to be adjusted from 4 lanes to 6 lanes after updating the development orientation of the Lao Cai – Hanoi – Hai Phong – Quang Ninh economic corridor.

In addition, at the request of localities, the Department of Roads proposed to adjust the range of the end points of the Ninh Binh - Hai Phong, Cam Lo - Lao Bao, Quy Nhon - Pleiku, and Ho Chi Minh City - Moc Bai expressways.
