The legacy of the Soviet Union lives on in the infrastructure of Central Asia. As it crumbles, or gets patched up, much of what was built in Central Asia is the backbone of the existing infrastructure for transportation, goods delivery and energy distribution. Much of the industrial infrastructure underwent precipitous decline in the 1990s, after the fall of the Soviet Union, especially in Kyrgyzstan and Tajikistan. The roads, railroads and energy lines are thus oriented towards the Russian Federation and away from other regional neighbors, such as China, Afghanistan or Iran.
