evidence: Construction on the single-tube, bidirectional tunnel had begun in 2011. Hundreds of engineers, geologists, and laborers took part in this project. Measuring 5.8 miles (9.3 kilometers) in length, this structure is India’s longest road tunnel. As a part of National Highway 44 (NH 44), the tunnel serves as a key connection between Chenani and the village of Nashri. [...] Known as the Chenani-Nashri Tunnel at the time of its opening, this structure has since been renamed the Dr. Syama Prasad Mookerjee Tunnel in memory of a prominent statesman, lawyer, and academician. Syama Prasad Mookerjee (1901-1953) served as India’s first minister of commerce and industry after the country achieved independence from British rule in 1947.
