Turkmenistan right-angle bridge

The Kerki-Kerkichi Bridge is a major railway and highway bridge over the Amu Darya River in eastern Turkmenistan, connecting Atamurat (Kerki) and Kerkichi.

Overview

The Kerki-Kerkichi Bridge spans 1,414 meters across the Amu Darya River in Lebap Province and serves both railway and highway traffic, making it a critical transport link in Turkmenistan's eastern region . Construction began under President Saparumurat Niyazov and was completed during President Gurbanguly Berdimuhamedov's tenure, with the first passenger train crossing in 2011 . The project cost approximately $123 million and was built by the Ukrainian Ukrtransstroy Bridge Building Corporation in collaboration with Turkmen builders .

Engineering and Design

The bridge was developed by the Ukrainian Institute Dneprogiprotrans and designed to withstand earthquakes up to 8–9 on the Richter scale . German experts contributed to the design of special bearings and anti-seismic devices, while an individual expansion joint accommodates longitudinal displacement and vibrations up to 1,000 mm . These features make the bridge one of the most complex and strategic construction projects in Turkmenistan .

Strategic Importance

The bridge is considered the largest and most complex in the region, providing a vital connection for both road and rail transport. It supports Turkmenistan's long-term goal of becoming a transport and logistics hub in the East-West and North-South corridors, integrating with highways, railroads, and the Turkmenbashi seaport . Its construction has significantly improved regional connectivity and economic development in Lebap Province.

Additional Context

Turkmenistan has been actively modernizing its road and bridge infrastructure, with around 200 bridges currently in operation and a highway network of approximately 14,000 kilometers . The Kerki-Kerkichi Bridge exemplifies the country's commitment to strategic infrastructure development and international collaboration in engineering. In summary, the Kerki-Kerkichi Bridge is a landmark infrastructure project in Turkmenistan, notable for its dual-purpose design, earthquake-resistant engineering, and strategic role in regional transport and logistics .
