3. APPROACH AND
METHODOLOGY

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

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.

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
Before After
Air
pollution
High (excessive) level
of pollution at ferry
landings from vehicle
queuing.
Low emissions at bridge.
Some increase from traffic
growth.
Water
pollution
High level of pollution from
vehicle & human activity by
the river,
and from the ferry.
Water runoff much less
polluted.
Noise High level of noise at ferry
landings.
Noise now reduced and
more distant from most
people.

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. Lessons
 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.

20. Conclusion
 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
