Upgraded highway aids Tajikistan’s economy

The mountains of Tajikistan in central Asia are home to several endangered species, including the snow leopard, the golden eagle and the rare markhor, an imposing wild goat. Glaciers high in the mountains bring water to the swift-moving rivers, which help irrigate farms.

Tajikistan’s economy is built on agriculture, but due to the poor condition of the roads, farmers often had difficulties transporting their perishable goods to buyers. To reduce rural poverty, expand the economy, and encourage agricultural and industrial exports, the country decided to undertake an ambitious program to upgrade its primary road network.

Working with the government of Tajikistan and the Asian Development Bank, Louis Berger was chosen to rehabilitate a 250-kilometer road that links the capital city of Dushanbe to Kurgan Tyube, Dangara and Kulyab. Last rehabilitated in the 1970s, the road was in very poor condition. Louis Berger designed and supervised the upgrade of road structures, embankments and damaged drainage areas on a section of the road totaling 80 kilometers.

The Louis Berger team also:

  • Provided design standards to minimize impacts on the country’s fragile environment while providing essential transport facilities.
  • Developed innovative erosion control protections to alleviate drainage and soil degradation.
  • Created a program for monitoring air and water quality and noise pollution.
