My Thuan Bridge Impact Monitoring Study

This study analyzes the impact of the My Thuan Cable-stayed Bridge on the economic, traffic, social, and environmental aspects, as well as bridge management. It includes baseline data, water quality testing, bridge inspection, and maintenance. The study uses various methods, such as surveys and data analysis, to assess the before-and-after effects of the bridge.

  1. My Thuan Bridge Impact Monitoring Study

  2. My Thuan Cable-stayed Bridge

  3. APPROACH AND METHODOLOGY

  4. Planning of Monitoring Activities: Criteria: economic, traffic, social, environment, bridge management. Baseline data: Socio-economic profile for provinces (1993). Traffic at My Thuan from Feasibility Study. Socio-economic data for bridge communes Water quality testing during feasibility and project construction. Bridge inspection and Maintenance manual. The Selection of Methods

  5. Define the contents of January 2001, July 2001, January 2002, July 2002, January 2003 and Final (July 2003) reports. A comprehensive methods/techniques for time series and cross section data collection: - Statistical data from GSO and Mekong delta provincial statistical office. - Delphi survey: + key informants (local authorities, managers of industrial zones, head of communes/villages, head of local association etc), Road Authority VII, Bridge and Road Maintenance Company 715, Manager of various ferries station in the Mekong delta etc.

  6. + Focus groups interviews: people who are primarily dependent on the MT ferry, former ferry employees, other people who gained a livelihood from the ferry. - Household questionnaire design. - Count & observe: change of shops along access roads to the MT bridge and between HCMC and MT bridge, number of vehicles using the bridge (Original –Destination traffic surveys), number of advertisement boards around the bridge etc.

  7. Comparison technique: before/after project Data analysis and writing up: - Set up the tables, figures, graphs, boxes and other annexes necessary. Using advanced excel and/or econometric techniques for data analysis (e.g. analysis of O-D traffic survey, using various data drawn from survey/questionnaire to present in the tables/graphs. Discussion/workshops/comments (during the writing up of the reports.

  8. STUDYFINDINGS

  9. Average daily traffic in 2002

  10. Origin/Destination of travel 64% 27% 36% 73% Car, van & bus passengers Motorcycle passengers Tien Giang Tien Giang Hau Giang Hau Giang 25% 33% Industrial goods 75% 67% Agricultural goods Tien Giang Tien Giang Hau Giang Hau Giang

  11. Growth in traffic crossing the Tien Giang at My Thuan

  12. Directional growth in freight My Thuan Bridge 12% 16% 17% Tien Giang 18% Hau Giang Average annual growth in freight movement (1994-2002)

  13. Forecast vs actual traffic

  14. Benefits to travellers

  15. Economic development • The Delta is industrial-ising, but agriculture is still important • GPP/capita has risen faster in the Delta than in HCMC • GPP/capita in the Delta is still well below that in HCMC • Economic growth in the Delta has been similar to that used in the Feasibility Study

  16. Development of industrial zones 20% of economic activity in Delta is from industry (46% in HCMC) 6 industrial zones are proposed for Dong Thap and Vinh Long provinces Sa Dec zone Commenced in 1999 Good progress My Thuan Bridge (15 km away) viewed as being important

  17. Environment

  18. Social impacts and transition • Former ferry employees redeployed (to bridge and other ferries) • New markets constructed at Hoa Hung & Tan Hoi to provide alternative employment opportunities for vendors • Vendors relocating to the new markets faced a difficult first 6 months, but conditions improved as the new markets became established – shops on road approaches increased from 160→540 • Elimination of delays at ferry landings has reduced loitering, improved personal security and reduced opportunity for spread of sexually transmitted diseases • Better access to social services because of ease of crossing the river and lower costs

  19. Support should be provided for the development of systems for inspection and maintenance of infrastructure and management of incidents. Programs to monitor the performance of projects should be designed and initiated ahead of project completion to ensure the availability of up-to-date baseline data. Actions to address the needs of those adversely affected by replacement of the former ferries need to be an integral part of such projects. Detailed consideration should be given to complementary projects that are needed to ensure consistent network capacity. Tolls set on a more explicit basis to ensure financial sustainability. Lessons

  20. Bridge built within budget and completed ahead of schedule Considerable technology transfer to Vietnamese partners Forecast demand has been substantially exceeded, especially motorcycles and person movement Considerable benefits from the bridge Greater-than-expected benefit due to higher traffic Development along access roads and economic growth Satisfactory transition for people affected Former ferry employees redeployed More difficult transition for vendors, but new markets now better established Positive environmental and social outcomes Reduced noise and emissions Improved access to local services Delays eliminated, resulting in less loitering and improved personal security Conclusion
