1. The South Asia’s First Underwater Tunnel Of Bangladesh
BANGABANDHU SHEIKH MUJIBUR RAHMAN TUNNEL
Presentation By Mohammad Minhaz Chowdhury

2. INTRODUCTION
Chittagong is the major port city and the gateway of
Bangladesh. It is also the second largest city and the
“commercial capital” of the country. The Karnaphuli River
divides Chittagong City into two parts (Figure 1.1-1). One part is
confined with the city and the port, the other part is the area of
heavy industry. The current two bridges are not sufficient to
accommodate the existing and increasing huge traffic flow. Due
to river morphology, siltation on the bed of the Karnaphuli River
is a big problem and the major threat for proper functioning of
the Chittagong Port. To face the problem on siltation,
Bangladesh government intends to construct a tunnel crossing
the Karnaphuli River instead of another bridge over the same
river. Bangladesh Bridge Authority (BBA) was entrusted to
implement the project. China Communication Construction
Company Ltd joint ventured with Ove Arup & Partners Hong
Kong Ltd (CCCC-Arup JV, the Consultant) was awarded the
project on 19th April 2011. Project kick-off meeting was held on
30th May 2011 and a site visit along Karnaphuli River was
arranged on 31th May 2011. Meetings with Road and Highway
Department and Chittagong Development Authority were held
before site visit. The inception report of the project was
submitted on 15th June 2011 and approved by the clients on
13th July 2011. The interim report was submitted on 3 November
2011 and approved on 8 April, 2012. The draft final report was
submitted on 30 July 2012 and approved on 17 April 2013. The
focus of the project is to carry out detailed economic and
engineering investigation to examine the economic viability and
technical feasibility for construction of tunnel under the
Karnaphuli River.

3. SERVICE AREA LIKE ‘RESORT’
A special part called 'SERVICE AREA' is being
worked on within this tension project. There will be-
 30 bungalows,
 A VIP bungalow,
 Motel mess,
 Health center,
 Grounds,
 Tennis courts,
 Convention center,
 The museum,
 Swimming pool,
 The mosque,
 Helipad.
There are so many benefits. Mr. Chowdhury said that
the work is going on near Parky Beach towards
Anwara. It will later be opened to the public as a
resort which will be a source of income for the
government, he said. 10,000 crores is included in the
project cost, although its construction has not been
completed.

5. Chittagong Division is located at the south east of Bangladesh.The Chittagong Division is known for its vast hilly
terrain and a tropical monsoon climate with much rainfall each year. Chittagong District and Chittagong City are also
shown in the right hand side of the figure. Please note the difference among Chittagong Division,Chittagong District
and Chittagong City.The former includes the latter. Chittagong City only represents the urban area in the western
area of the Karnaphuli River.Chittagong City is the second largest city in Bangladesh which at the same time is the
Commercial Capital City of Bangladesh, with a population estimated at over 5.74 million. Chittagong is located at
22°22’0”N, 91°48′0″E, south eastern in Bangladesh and northern on Sitakund, and is seated on the banks of the
Karnaphuli River, covering a total area of 168.07 sq km1.
Bangladesh and chittagong developed rapidly through a
market–based economy. Chittagong district, having the
largest port of the country, plays an important role in this
rapid growth.
The surrounding mountains and rivers make the city
attractive as an ideal vacation spot. Transport in chittagong
consists of various bus systems and taxi services. There
are also traditional manual rickshaws. Trains and the
national highway connects chittagong with the bangladesh
cities of dhaka, shylhet, comilla, and bhairav.

Design of Tunnel Structure
Cross-section Scheme
In order to meet the requirements for disaster prevention and rescue, interconnecting
passages between the left and right tunnels will be set up at a certain interval of around
600~700m, and the minimum distance between the two tunnels is considered as 1 time
of the tunnel diameter.
