After blocking the lane towards Fouzdarhat on Monday following rain-triggered landslide on parts of the road, the CDA on Wednesday closed the road completely for three months.
The authorities cut 18 hills along the road to develop it even after being fined for damaging environment.
As they were cut at a 90-degree angle, the hills now also pose a great risk of landslide.
“This place has become a tourist spot. So we didn’t want to take chances. After closing one lane on Monday, we’ve closed the entire road to the public today (Wednesday),” said Kazi Hasan Bin Shams, chief engineer at CDA.
The authorities in October last year sought permission from the Department of Environment to shave 200,000 cubic feet off the hills at a 45-degree angle and reduce the risk of landslide.
Hasan said they were making a report based on analysis by experts to cut the hills further. The CDA will also build retaining walls.
Once the project is complete, motorists can get to the Dhaka-Chattogram Highway from Kaptai, Rangamati, Hathazari, Rauzan and Rangunia without having to enter the port city.
Prime Minister Sheikh Hasina inaugurated the project implemented at an estimated cost of over Tk 1.72 billion in June, 2016.
The government later decided to make the road with four lanes instead of two, which inflated the cost to Tk 3.2 billon.
After serving two reminders in 2017, the DoE had fined the CDA Tk 1 million for causing environmental damage in implementing the project.
In February 2020, the department fined the development agency over Tk 100 million for damaging the biodiversity, surface soil, and binding capacity of the hills by razing them.
CDA cut 69,000 cubic feet more hills than the permitted level of 250,000 cubic feet.
It also flouted the hill-cutting management plan by razing the hills at an angle of 90 degrees.
During a visit in 2020, Environment, Forest and Climate Change Minister Md Shahab Uddin said he noticed that the constructors did not follow the rules on creating slopes while cutting hills.
Exploiting the restrictions on movement over the coronavirus outbreak, the encroachers have grabbed around 15 acres of land by cutting the hills further and constructed more than 400 illegal structure at different locations.
The district administration later cleared the places, but the encroachers are back now despite the risks of landslide.
