PALPA: The invert construction of the Siddhababa Tunnel—one of Nepal’s national pride projects—has been completed, according to Engineer Sabita Gyawali of the Tunnel Project Office.

The invert work on the 1,089-meter-long main tunnel was finalized on Wednesday. “We are now progressing with the lining phase. So far, 834 meters of lining work has been completed,” said Engineer Gyawali.

The Siddhababa Tunnel, situated in Tinau Rural Municipality-3 of Palpa district along the Siddhartha Highway, has recorded 56.3 percent physical progress and 50.24 percent financial progress. The project has accelerated significantly since achieving its tunnel breakthrough.

The 1,126-meter tunnel is designed to connect the Upper Siddhababa Temple along the Butwal–Tansen section of the highway, offering a safer alternative to a notoriously hazardous stretch of road.

Construction began in 2022 and is being executed by the China State Construction Engineering Corporation. The total project cost is estimated at Rs. 7.34 billion, which includes Rs. 2.14 billion allocated for additional work. Completion is targeted for 2026, marking a five-year construction period.

The stretch between Lower Siddhababa Temple and Dobhan in Palpa is known for frequent landslides and heavy dust, even in dry seasons. The tunnel is expected to significantly reduce risks and improve travel safety.

The Siddhartha Highway is a critical route for vehicles traveling to and from districts like Gulmi, Palpa, Arghakhanchi, Syangja, Kaski, Baglung, and Myagdi.

The tunnel is expected to be a game-changer in ensuring uninterrupted and safe transportation across these regions.
