In order to create a breakthrough in attracting investment and accelerating the development of the socio-economic infrastructure system, in the period of 2026 - 2030, Quang Ninh province is studying the Investment Project to build an inter-island traffic route in Van Don Special Zone.
The total length of the route is about 58.2 km. Including 9 bridges, with a total length of 14.2 km; 22 km of newly built and upgraded roads, and 22 km of the current Tan Lap - Ban Sen road.
Van Don Special Zone has hundreds of islands, including famous tourist islands, such as: Minh Chau, Quan Lan, Ban Sen, Thang Loi, Ngoc Vung...
There are 2 investment options.
Option 1, the width of both the bridge and the road is 12 m, with a total investment of about VND 8,570 billion. According to this plan, 9 bridges, with a total length of 14.2 km, have a total investment of about 7,100 billion VND; 22 km of newly built roads have an investment capital of about 990 billion and 440 billion VND to expand 22 km of the current Tan Lap - Ban Sen road.
Option 2, the width of both the bridge and the road is 24 m, with a total investment of VND 17,160 billion.
Of which, the cost of building 9 bridges is about 14,200 billion VND; about 2,000 billion VND for 22 km of newly built roads and 960 billion VND to expand 22 km of the current Tan Lap - Ban Sen road.
In the plan to build transport infrastructure, socio-economic infrastructure in Van Don Special Zone and Co To Special Zone synchronously and modernly, ensuring both promoting socio-economic development and consolidating and firmly strengthening national defense and security, in the period of 2026-2030, Quang Ninh province also plans to build a sea overpass connecting the large Co To island and Thanh Lan island, belonging to Co To Special Zone.
This bridge is about 2 km long and is expected to be implemented from 2027-2029.
Currently, the means of transportation between these two islands are boats and ferries, with a one-way time of about 20 minutes under normal weather conditions.
Thanh Lan Island, 27km2 wide, is the largest island in the Co To archipelago, holding a particularly important strategic position in the Gulf of Tonkin. On the island, there are about 1,600 people who live mainly by fishing, and have started exploiting tourism.
