Subhash Barua, vice-president of planned Chittagong forum and urban planner, said that the traffic congestion will increase if the tunnel vehicles come out. Thousands of trucks-covered vans are bringing goods to and from Chittagong port every day. He said that it is necessary to look at how these vehicles can be brought under proper management. Harunur Rashid said that this type of tunnel under the river is the first in South Asia. Massive efforts are on to complete the remaining 4 percent of the project. Project officials said that on October 14, 2016, Bangladesh Prime Minister and Chinese President Xi Jinping laid the foundation stone of the project. Prime Minister Sheikh Hasina officially inaugurated the construction of ‘Bangabandhu Sheikh Mujibur Rahman Tunnel’ on February 24, 2019. The tunnel starts near the Patenga Naval Academy in Chittagong city and rises through the middle of the Karnaphuli river to the Anwara end of the south bank. The tunnel will reach the southern end of the river passing between the factories of Chittagong Urea Fertilizer Limited and Karnaphuli Fertilizer Limited. The tunnel will be located in the middle of the Karnaphuli river at a depth of 150 feet. The construction of the tunnel is being done by the Chinese contractor Communications Construction Company. The cost has been estimated at 10 thousand 374 crore 82 lakh taka. 210 Chinese citizens and 800 Bangladeshi workers are working day and night to implement the project. According to the project source, the construction of this tunnel under the Karnaphuli river is going on at a cost of 10 thousand 374 crore 82 lakh taka. Out of this, China’s assistance is 5 thousand 913 crore 19 lakh taka. Bangladesh government is giving four thousand 461 crore 23 lakh taka. Exim Bank of China has given this loan at 2 percent rate for 20 years. Chinese contractor China Communication and Construction Company Limited (CCCC) is implementing the tunnel construction project. Chinese companies will maintain and collect tolls for the tunnel project. The Cabinet Committee on Economic Affairs meeting on 18 May 2022 approved in principle the proposal to appoint China Communications Construction Company Limited (CCCC) for this work. The government led by Prime Minister Sheikh Hasina took the initiative to build this tunnel under the Karnaphuli River to connect the Patenga and Anwara upazilas of South Chittagong to turn the port city into a ‘one city, two town’ model like Shanghai in China.
