1. Introduction The project road is located in the northwest region of Hanoi City, which is divided by Hong River. The insufficient bridge infrastructure across the river hinders brisk inter-regional activities in the region. And traffic congestion in/around Hanoi City reaches to serious situations as all vehicles across the river shall pass through the roads in/around Hanoi City due to the road network shape in which radial corridors (National Highway No.2 and No. 32) are dominant. According to the Hanoi Capital Regional Plan (No.490/QD-TTG) approved by the minister of Ministry of Transport on 5 May 2008, Ha Tay and Vinh Phuc provinces were planned to be developed as centers for high-technological, industrial, tourism and residential activities. However, with the current insufficient bridges passing over Hong River, it is likely to be hard to achieve such development goals. Thereon, the construction of the Vinh Thinh Bridge as a section of Ring Road No.V, which will be a circular road network around Hanoi City, is set to be one of the top priorities in the road network construction plan of the Vietnamese government. Besides the Vinh Thinh Bridge project is already included into the infrastructure development plans such as the Decision No.162/2002/QD/TTg 1) and the Decision No.1290/QD-TTg 2) announced by the Prime Minister of Vietnam on 15 November 2003 and 26 September 2007, respectively. 2. Objectives Objectives of this project is to increase the accessibility for residents; to reduce vehicle travel times and vehicle operating costs; and to alleviate traffic congestion in/around the Hanoi City by linking Ha Tay and Vinh Phuc provinces with the Vinh Thinh Bridge. It also focuses on reducing logistic costs, encouraging lower poverty ratio in the region, and improving living conditions by activating exchanges in people and goods between the two provinces. It will also promote the growth of industrial complexes located in Vinh Phuc, Yen Bai and Puc Yen. 3. Work Scope The project area is located in around
40km northwest from the Hanoi City center and the work scope of the Feasibility Study (FS) Project is as follows: Direct influenced area : within 10 km radius around the project section Indirect influenced area : northwest region of Vietnam The base year of the FS analyses is the year 2008, and the target year is the year 2032 that will be after 20 years from the opening year (2013) of the Vinh Thinh Bridge (The construction period is assumed as 3 years.). The scope of work of the FS comprises of two main parts. They are as follows: to conduct a feasibility study for about 9.05km connecting Ha Tay province and Vinh Phuc province considering engineering, economic, social, road safety and environmental aspects based on the Pre- Feasibility Study conducted by MOT, 2005. to supply necessary information for the EDCF loan appraisal mission after the FS by collecting and analyzing relevant data. The FS was carried out for 3 months from 30 April to 29 July 2008 in accordance with EDCF Feasibility Study Guideline, Korea EXIMBank, 2007. www.yooshin.co.kr

4.2 Traffic Demand Forecast Statistical data, road network data, and origin-destination data of The Study on the National Transport Development Strategy in the Socialist Republic of Vietnam, JICA, 2000 were used as the basic data for traffic demand forecast in this project. Because no substantial data or information was available in the Pre- Feasibility Study about the traffic demand forecast for the proposed construction project. The future traffic demand is forecasted as 5,552 pcu/day in 2013 and as 33,716 pcu/day in 2032. Annual traffic growth rate is expected at around 10%. The future traffic volumes are summarized as the table below. <Forecast Future Traffic volume> (Unit : pcu/day) Year Car Bus Truck Motorcycle Sum 2013 1,381 1,717 1,351 1,103 5,552 2014 1,594 1,877 1,470 1,163 6,104 2015 1,833 2,053 1,600 1,226 6,712 2016 2,102 2,246 1,741 1,293 7,382 2017 2,402 2,456 1,895 1,363 8,116 2018 2,740 2,687 2,062 1,437 8,926 2019 3,117 2,939 2,244 1,515 9,814 2020 3,538 3,214 2,442 1,597 10,792 2021 4,009 3,515 2,658 1,684 11,866 2022 4,536 3,845 2,892 1,775 13,048 2023 5,188 4,176 3,126 1,859 14,348 2024 5,918 4,535 3,377 1,946 15,776 2025 6,735 4,926 3,650 2,037 17,348 2026 7,648 5,349 3,944 2,133 19,074 2027 8,669 5,810 4,262 2,233 20,974 2028 9,810 6,310 4,606 2,338 23,064 2029 11,082 6,853 4,977 2,447 25,360 2030 12,502 7,443 5,379 2,562 27,886 2031 14,083 8,084 5,813 2,683 30,662 2032 15,847 8,779 6,281 2,809 33,716 Growth rate 13.7% 9.0% 8.4% 5.0% 10.0% www.yooshin.co.kr

4.5 Economic Analysis The economic analysis for the project was conducted according to the EDCF guidelines using internationally accepted methods. The result of the economic analysis shows that all the alternatives are economically feasible because the B/C ratios for all the alternatives are over 1.0. Alternative 3 has the highest EIRR, 17.65%, and is estimated as the best alternative as far as economic feasibility. However, it is evaluated that any alternative among Alternative 1, 2, 2-1 and 3-1 can be selected in view of the policies because the EIRRs of the alternatives are almost the same (within 1% point difference). Excluding Son TayBypass Section Including Son TayBypass Section Alternative B/C NPV EIRR Alternative 1 (Phase construction) 1.70 58,341,540 16.37% Alternative 2 (4lane construction) 1.94 84,285,863 17.42% Alternative 3 (Phase construction) 1.99 85,799,725 17.65% Alternative 2-1 (4lane construction) 1.80 77,343,011 16.75% Alternative 3-1 (Phase construction) 1.84 78,745,405 16.94% Financial analysis was not conducted in the FS because the project road is not a toll road. 4.6 Environmental Analysis Environmental impact analysis in the FS on the Vinh Thinh Bridge construction project was followed by EDCF Feasibility Study Guidelines, Korea EximBank, 2007. According to the Guidelines, the project is classified as Category B Therefore Environmental Impact Assessment (EIA) for the project is not necessary. According to Vietnamese regulations, however, EIA for the project should be conducted in the stage of Feasibility Study. In the situation, it was conclude during the 2nd Field Survey and the MOT Meeting on 4 June 2008 that the environmental impact analysis for the FS on the Vinh Thinh Bridge construction project do follow the EDCF guidelines. At the same meeting, it is also concluded that EIA followed by Vietnam regulations will be conducted by TEDI, a local engineering company, for acquiring approval of the FS from relevant central ministries. It is analyzed that the project produces no serious factors to cause negative www.yooshin.co.kr
impacts on its surroundings or residential area because the selected route alignment passes mostly farm lands with a little residential areas. And appropriate mitigation measures on expected negative impacts was suggested for minimizing negative impacts 4.7 Resettlement Plan roughly estimated using the updated topographic map(1:5,000) and unit values of land acquisition and compensation costs. In the case of Alternative 3, total land acquisition and compensation cost is estimated as USD 2,862,853. 4.8 Financial Plan of the Vietnamese Government The resettlement plan in the FS on the Vinh Thinh Bridge construction project was conducted based on EDCF Feasibility Study Guidelines, Korea EximBank, 2007. During the 2nd Field Survey and the MOT Meeting on 4 June 2008, the work for establishing the resettlement plan followed by Vietnam regulations was assigned to TEDI in order to get approval on the Vinh Thinh project from relevant ministries. Quantities of land acquisition and compensation affected by the project were Taking into account financial resources of the Vietnamese Government and uncertainty of private invested projects, this project was classified to be financed with Korea EDCF loan. 4.9 Project Implementation Plan Detailed Design and Land Acquisition : 2009 Construction Period : 2010 ~ 2012 (3 years) Item Selection of Consultant 2009 2010 2011 2012 3 6 9 12 3 6 9 12 3 6 9 12 3 6 9 12 Detailed Design Land Acquisition Selection of Contractor Construction Construction Supervision
