On September 5, 2026, the first tunnel on the Chinese-Kyrgyz-Uzbek railway in Kyrgyzstan – Koshtber North Tunnel No. 2 – was successfully completed. The tunnel is 209.6 meters long. Construction began on May 10, 2026, and it was completed in just 87 days, with a maximum burial depth of 41 meters. At the same time, the tallest bridge on the line, the Kech Alete River Bridge (with a total length of 956.67 meters), is also under construction simultaneously. The Chinese-Kyrgyz-Uzbek railway is a landmark project promoted by the heads of three countries under the “Belt and Road” initiative. The line starts from Kashgar in Xinjiang, China, passes through the Kyrgyzstan section (with a length of 304.84 kilometers, accounting for nearly 60% of the total length), and ends in Ankabad in Uzbekistan. Due to complex geological conditions in Kyrgyzstan, 29 new tunnels and 50 bridges need to be built, with a total length of about 120 kilometers. This section is the most challenging to construct along the entire line.

“The first tunnel in Gyeonggi Province was completed along the China-Gyeonggi-Uzbekistan railway”
The first tunnel in the Gyeonggi-Ussuri railway section within Gyeonggi Province has been completed, and construction on the highest bridge along the line is also progressing simultaneously.
The first tunnel in the Kyrgyzstan section of the China-Kyrgyzstan-Uzbekistan railway was completed, and construction on the highest bridge along the line is also progressing simultaneously. The Koshtber North No. 2 tunnel, with a length of 209.6 meters, is a single-tunnel, single-track tunnel with a maximum burial depth of 41 meters. Construction began on May 10, 2026, and the team completed the tunnel completion in just 87 days. Meanwhile, key projects such as the Naren No. 1 tunnel have also achieved phased results. The China-Kyrgyzstan-Uzbekistan railway is a landmark project promoted by the heads of three countries under the “Belt and Road” initiative. The project starts from Kashgar in Xinjiang, China, passes through the Torgat Pass into Kyrgyzstan, extends westward through the border city Jala Labad, and ends in the eastern city of Andijan in Uzbekistan. The railway has a total length of over 500 kilometers, of which the section in Kyrgyzstan is 304.84 kilometers long, accounting for nearly 60%. The Kyrgyzstan section is the most challenging for construction along the entire line, requiring the construction of 29 tunnels and 50 bridges, with the total length of bridges and tunnels reaching approximately 120 kilometers, nearly 40% of the total length of the line. Among them, the highest bridge along the line – the Kech Alete River Bridge – has a length of 956.67…
