The Southern major economic region consists of 8 provinces and cities which are Ho Chi Minh City and the provinces of Dong Nai, Binh Duong, Ba Ria – Vung Tau, Tay Ninh, Binh Phuoc, Long An and Tien Giang. This economic region has a dynamic development with high growth, holds the leading position in some important industries such as import-export and production of consumer goods, attracts foreign investments, develops centralized industrial zones and product processing zones, contributing to improve the competitiveness of the economy, create the development driving force for the region and attractions to neighboring areas.
Figure 1 – Project location
This region is the transport center with all types of transport including domestic and international highway, railway, waterway, and airway.
For Ring Road No.3, because of its importance in creating the regional development driving force, the Prime Minister approved the detail planning of Ho Chi Minh City Ring Road No.3 at Decision No. 1697/QD -TTg dated 28/9/2011. Accordingly, the entire ring road No. 3 has the length of 89.3 kilometers passing Ho Chi Minh City and 4 provinces of Dong Nai, Binh Duong and Long An.
Because the total investment of Ho Chi Minh City Ring Road No. 3 is very high, in order to facilitate the mobilization of legal investment capitals, the road is divided into independent components, of which Component 1A is the investment project on construction of the section from Provincial Road No. 25 to Ho Chi Minh City – Long Thanh – Dau Giay expressway.
Figure 2 – Project location
Component 1A, Tan Van – Nhon Trach section of Ring Road No. 3 has the length of about 8.75 kilometers with the starting point at the interchange with the provincial road No. 25B in Nhon Trach district, Dong Nai province, and the ending point at the interchange with HCM City – Long Thanh – Dau Giay expressway in Thu Duc City, Ho Chi Minh City. The work is planned to have following scales:
– Road class:
+ Urban expressway (design velocity V = 100km/h)
+ In phase 1, the road will have the scale equivalent to the plain road class III according to the standard coded TCVN 4054-2005, with design velocity V = 80km/h;
– Typical cross-section: 4 motorized lanes and 2 mixed lanes
– Road junction: 3 intersections with provincial roads and 1 interchange with HCMC – Long Thanh – Dau Giay expressway
– Bridge: 2 bridges and 4 viaducts of frontage roads
– Toll plaza: 01 toll plaza
– Lighting: Lighting system shall be arranged along the route alignment.
