1st reinforced-concrete segments anchored at Thu Thiem Tunnel
HCM City (VNA) – The first of the four reinforced-concrete segments was anchored at the construction site of the Thu Thiem Tunnel on the Sai Gon River on Mar. 7.
The 27,000-tonne structure will be settled in the river bed on march 9, while the
other three segments will be towed to the site later from Nhon Trach District in
the southern province of Dong Nai .
The 370.8-metre long underwater tunnel will connect the city’s District 1 with
the new urban Thu Thiem Area in District 2. The tunnel is designed to ease the
east-west traffic flow in the city.
Experts said the sealed segment will be lowered into a prepared trench on the
riverbed and then covered with backfilling material in order to secure its
position and protect the tunnel.
The installation of each unit takes about one month to complete.
After the four units are secured and connected with the tunnel entrances at both
ends, the driveway and the emergency pathways will be paved and assorted
installation projects will continue until the tunnel is completed and opened in
mid-2011.
The tunnel is part of the Sai Gon East-West Highway Project that is being
implemented by HCM City with financial assistance from the Japan
International Cooperation Agency (JICA). The agency has provided 41.027 billion
yen (456 million USD) in ODA for the project.
Addressing a press meeting on March 7, Tsuno Motonori, chief representative of
JICA Vietnam Office, said this was the first infrastructure project supported by
JICA in HCM City .
This new six-lane, 22-km road will connect National Highway 1A with the
Hanoi Highway in the east. The road will also pass under the Sai Gon River
through the Thu Thiem tunnel.
The western part of the highway opened to traffic to September 2 last year.
Four bridges over the canal Khanh Hoi, Calmette, Chu Y and Cha Va , also
opened last year.
The road section on the Thu Thiem side will be gradually opened starting in
April this year.
Motonori said the installation of the immersed tunnel units is the most difficult
part of the EWH project. He added that these are the first immersed tunnels in
Vietnam and also the first project of this type in Southeast Asia.-Enditem.
