Project Description

The project involves the construction of the tunnel and approach roads which are split into two distinct sections. One is located on the north western side of the Karnaphuli River and the other on the southern eastern side of the river. The project route has a total length of 9,266 m. The approach road on west bank is 550 m long, including the toll plaza which is 400 m long. The main structure is 3,315 m long (the open section on west bank is 200 m long, buried section on west bank 195m long, working shaft on west 25 m long, shield section 2,450 m long, working shaft on east bank 25 m  long, buried section on east bank 230 m long, open section on east bank 190 m long). The approach road on east bank is 5,400 m long (including the 750 m long viaduct and 400m long toll plaza), the river where it is crossed by the tunnel is about 1,240 m wide.
