Phu Yen (VNA) – The two ends of the 4.1-kilometre Ca Pass Tunnel, the country’s key infrastructure project that crosses the central provinces of Phu Yen and Khanh Hoa, was ​connected on July 31.

The project aims to replace Ca Mountain Pass and Co Ma Mountain Pass, parts of National Highway 1A, that run through Dai Lanh Mountain and have dangerous bens prone to avalanches and landslides.

​The facility includes two parallel tubes, began in September 2014. Its tunnelling was completed two months ahead of schedule. Construction cost 12 trillion VND (533 million USD) instead of 16 trillion VND as initially planned thanks to technical design change.

The tunnel will help shorten the time passing the Ca Pass by 80 percent, contributing to reducing accidents and traffic congestion.

Addressing the event, Deputy Prime Minister Trinh Dinh Dung hailed efforts made by the investor and contractors to complete the tunnelling.

He asked the Ministry of Transportation to work with relevant agencies to provide the best conditions for the investor to operate and maintain the work effectively.
