Vietnam i s c urrently e xperiencing rapid e conomic g rowth, b ased p rimarily o n e xport p rocessing industries and tourism. Between 2003 and 2009 gross domestic product (GDP) grew by an average of 8% per year, while exports in the same period grew by an average of about 20%. The Mekong Delta region, where the proposed Project is located, is the third-largest industrial centre in the country after Ho Chi Minh City (HCMC) and Hanoi, and is based primarily on agro-industry and other light industries. Industrial production in the Mekong Delta region has accelerated in recent years, from an average annual growth rate of 13% in the period 2000–2004 to a growth rate of 24% in 2004–2005, and 25% to 2010. 2. As a result of this economic growth, road traffic is also growing rapidly and is a key constraint to future development. Between 2000 and 2009, for example, passenger traffic grew at an average rate of about 11% per year and freight traffic at an average rate of about 12%. The Government of Viet Nam is upgrading and expanding Vietnam’s strategic transport infrastructure – including the road network. 3. The ultimate project, shown in Table 1.1 and on the map in Figure 1 will improve connectivity in the Mekong Delta Region and provide efficient access from Ho Chi Minh City to the Southern Coastal Region through construction of high cable-stayed bridges across the Mekong River and associated roads: Table 1.1: Central Mekong Delta Region Connectivity Project Components April 2010 Component Location Standard Lengths 1 Cao Lanh bridge and NH30 Interchange (km31+080) to Road 4 lanes. 7.8km approach roads interchange with PR849, Bridge 4 lanes and (bridge 2.1km) including interchange 2 lanes for two- wheelers 2 Cao Lanh – Vam From the end of Component 1 to 4 lanes 15.7km Cong Interconnecting
