The Bangladesh government has approved a Tk1,183 crore highway project to develop a new economic corridor through the Karnaphuli Tunnel, according to verified reports from local news sources as of June 2026. The project aims to improve connectivity and boost trade in the region.
The Karnaphuli Tunnel, also known as the Bangabandhu Sheikh Mujibur Rahman Tunnel, is a 3.4-kilometer underwater tunnel under the Karnaphuli River in Chattogram. It is the first underwater tunnel in South Asia and was inaugurated in 2023. The new highway project will link the tunnel to key economic zones.
Officials stated that the project will facilitate transportation of goods and passengers, reducing travel time and costs. It is expected to enhance economic activities in Chattogram and the surrounding areas, creating a new corridor for regional development.
