ya, there were a bunch of trade routes along this path to all the different regions/cities. We just named the entire concept the "Silk Road" in the 1800s (it was coined in 1877 by Ferdinand von Richthofen).
"While engaged in a survey of China, the baron was charged with dreaming up a route for a railway linking Berlin to Beijing. This he named die Seidenstrassen, the Silk Roads. It was not until 1938 that the term Silk Road appeared in English, as the title of a popular book by a Nazi-sympathising Swedish explorer, Sven Hedin."
