Construction of the tunnel on a highway that links Tibet’s Metok County to the outside world was completed when explosives blasted through the final section at 10 a.m. Wednesday, China’s Xinhua news agency reported.
The construction crew announced the success of the blast, which took 152 kg of explosives, and workers from both ends met at 10:28 a.m.
It took construction workers more than two years to complete the construction of the 3,310-meter Galongla Tunnel, built at an altitude of 3,750 meters.
It is part of a planned highway that will link Metok County to the outside world, which is scheduled to be finished by the end of 2011.
Metok County, with a population of 11,000, is China’s last county with no highway link.
Snow and rain make the mountain roads impassable for nine months of the year, and the walk out of the mountains can take about 10 hours.
The 117-km Metok Highway, linking Bome and Metok counties, will shorten the time dramatically as the journey through the tunnel will take just half an hour.
