I.1.2.2 Construction scale of resident roads and rural roads in corridor 3 – phase 2
NW11: Commenced point at Km207+000 and end point at Km248+500 (as per alignment of waterway),
total length shall be of 41.5km, total length subject to dredging shall be from Km220+500 to
Km238+000. There shall appear no traffic roads and bridges for rural transport system which
shall be damaged during dredging works.
NW12: Commenced point at Km248+500 and end point at Km290+000 (as per alignment of waterway),
total length shall be of 41.5km, total length subject to dredging shall be from Km264+500 to
Km290+000; total length subject to site clearance shall be from Km285+400 – Km290+000.
Commenced point at Km282+500 to the end at Km287+575, Bac Lieu province has the project
tittled “Embankment on the two sides of Bac Lieu river. If this project is conducted before WB5
project, pedestrian roads along this section will not necessarily re-built because WB5 project lies
in the area of the Embankment project.
Accordingly, the scope of construction for pedestrian roads will be the construction of 2,479 m of
pedestrian roads and re-building of 2 padestrian bridges.
Because the clearance area lies on the Southern bank and big funding requirement for
“Embankment on the two sides of Bac Lieu River” project, Bac Lieu province currently has
insufficient funding. The duration for the embankment project is not clearly fixed, especially when
the Southern bank is allowed by the province to be complete later than the Northern bank.
Therefore, in the design report for WB5 project, re-construction of bridges and roads is still
mentioned. The scope of construction for pedestrian bridges from Km282+500 to Km287+575
will be:
From Km285+400 – Km290+000 at left bank (south bank), including 05 rural bridges to rebuild
and total length of resident roads refurbished shall be of 3.823km;

NW13: Commenced point at Km290+000 and end point at Km310+000 (as per alignment of waterway),
total length shall be of 20.0km, total length subject to dredging shall be from Km290+000 to
Km309+750 of which from Km290+000 – Km301+000 which shall subject to dredging and
destruction of roads and bridges along left bank including 11 resident bridges which shall be
refurbished and with total length of resident roads refurbished shall be of 8.380km.

II. NATURAL CONDITIONS
II.1
TOPOGRAPHICAL AND GEOMORPHOLOGICAL CONDITIONS
General description of the topography of the two corridors is given specifically in the Description on
dredging design. In this description on pedestrian roads, only topographical and geomorphological
features at river and canal sections that need site clearance and re-construction of previous roads are
given.
II.1.1
TOPOGRAPHICAL CONDITIONS OF CORRIDOR NO. 2
Waterway corridor No 2 is divided into sections, depending on the location and is specifically described
as bellows:
Section NW8. From Km00+000 to Km37+000 – Te canal
 Km00 is the location where Te canal connects with Sai Gon river leading to Doi canal, Tau Hu canal,
Cho Dem river, Ben Luc river to Vam Co Dong river. This section is dredged and cleared. However,
this section does not contain any pedestrian roads, just some temporary ways that are not considered
to be as roads. Moreover, this section will be built with anti-tide dikes. Therefore, no pedestrian roads
will be formed here.
Section NW9. From Km37+000 to Km50+700 - Thu Thua canal
 Ending part crossing Vam Co Tay river. It shall be in Thu Thua district – Long An province. It shall be
densely covered with resident houses and works along both banks in Thu Thua town area, apart from
this there shall be quite low densed coverage of houses and construction works. There shall be many
wild coconut trees in some parts along both banks of canal. This part of canal shall be in rural area,
there shall have areas for rice feeding, farming. Several rural roads appear along both banks.
 Width of river shall be varies in within (45 - 55)m, average bottom level shall be about from -3.00m to -

5.0m, quite straight and no bending parts of routine can be encountered.
 There appear several berths for goods intaking and ships. Some parts shall have embankment. There
shall be 3 over-river bridges, underground works and power wiring over river.
 Clearance and construction of traffic roads will be within Northern bank. Currently, there is a road
route from Km42+410 to Km43+273 running along the canal edge over a length of 863 m. The width
of this road is 2,0 m on average. The average level of the surface is between +1,8 to +2,4m
 Current structure of the road is soil structure
 There is a traffic road whose structure is illustrated in Chapter 3 of this report.
Section NW10. From Km50+800 to Km80+000.
 Not too many resident houses and construction works along both banks. There shall be many traffic
roads in some parts along both banks of canal. This part of canal shall be in rural area, there shall

shall result in complicated water table variation.
For finalization of water table as per frequency of service hours for transport purposes, hydrological
investigation has been performed/monitored at 21 stations at the same time for measuring water table in 2
corridors for 16 consecutive days. Of which water table in Rach Chanh creek has been measured at
upstream and downstream of culvert during dry season (May 2010) when Rach Chanh culvert gate was
closed for salinity prevention.
