Overview
Updated 1 hour agoWorkers holed through the 209.6-meter Kosh Dobo North No. 2 tunnel on August 5 after 87 days of boring. On September 5, the trilateral joint venture running the China-Kyrgyzstan-Uzbekistan railway announced the breakthrough — the first of 27 tunnels now under construction on the Kyrgyz section.
The railway will run more than 500 kilometers from Kashgar in China's Xinjiang region through Kyrgyzstan to Andijan, Uzbekistan. It ends Central Asia's rail dependence on Russia and gives landlocked Kyrgyzstan its first east-west corridor of its own.
Why it matters
This rail link gives Central Asia a direct trade route to China, bypassing Russia's rail network — construction is now physically underway, not just planned.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
Karakoram Highway (1959-1978)
China and Pakistan spent nearly two decades carving a 1,300-kilometer highway through the Karakoram and Himalaya ranges, connecting Kashgar to Islamabad. The route required blasting through some of the world's toughest mountain terrain and claimed hundreds of workers' lives.
Opened in 1978, it became the main overland trade and strategic link between China and Pakistan.
It set the template for China's high-altitude infrastructure ambitions across Central Asia.
Kashgar is the same starting point as the CKU railway — the new project extends China's mountain infrastructure push westward, swapping road for rail.
Qinghai-Tibet railway (2006)
China completed a 1,956-kilometer rail line from Xining to Lhasa, crossing permafrost at elevations above 4,500 meters. The final Golmud-to-Lhasa leg took five years and required special engineering for frozen ground.
Became the world's highest railway and a backbone of Tibet's economy.
China gained proven rail-engineering experience in cold, high-altitude, seismically active terrain.
The Tien Shan route on the CKU railway faces similar permafrost and seismic challenges, and Chinese contractors bring this track record to the project.
Baku-Tbilisi-Kars railway (2007-2017)
Azerbaijan, Georgia, and Turkey built an 826-kilometer rail line connecting the Caspian to Europe, deliberately bypassing Russia. Construction started in 2007 after years of planning and the line opened in 2017, a decade later, after repeated delays.
Provided a new east-west freight corridor through the South Caucasus outside Russia's rail system.
Showed both the strategic value and the difficulty of multi-country rail projects in the post-Soviet space.
The CKU railway follows the same logic — a trilateral rail link bypassing Russia — but on harder terrain and with a partner whose construction resources run far deeper.
