Tunnel T-4 Breakthrough Marks Major Progress in the Khurda Road–Balangir New Rail Line project

A major milestone in the Khurda Road–Balangir New Rail Line project was achieved on April 16, 2025, with the successful breakthrough (daylighting) of the 4,185-metre-long Tunnel T-4 between Adenigarh and Charichhak stations in Boudh district, Odisha.

This marks the completion of the longest tunnel not only in the entire project but also in the state of Odisha.

In the ongoing Khurda Road–Balangir New Rail Line project so far, 226 km of the total 301 km stretch has been commissioned—from Khurda Road up to Daspalla on one end, and from Balangir up to Purnakatak on the other. The remaining 75 km stretch between Daspalla and Purnakatak, which includes seven tunnels currently under construction, is progressing steadily.

The successful daylighting of Tunnel T-4 is a significant achievement that will accelerate the pace of construction and bring the project closer to its goal of connecting Odisha’s coastal region with its western hinterland—promoting seamless travel, regional integration, and economic development.
