Personally I don't think that the 'silk road' itself should be something that can be built, it is merely something that passes through some parthian provinces. However, parthian provinces that the silk road does pass through (not all parthian cities) should have a large trade bonus, and by building markets and merchants quarters, should be able to increase this substantially.

Actually, personally I'd be happier if the silk road was something that passed through seleucid provinces too, maybe as far as Antioch, and east as far as Kashgar, with each province it passes through getting a big trade bonus, it wasn't just the parthians who knew how to cash in on hungry tired merchants who have been travelling for months
The Persian Empire left the Seleucids and Parni with an excellent infrastructure. Persian runners invented the mail, remember. Persian engineers built great cities and roads ( see Persepolis) connecting all provinces of their empire. The Parthians have the same origins as the persians ( iranian origins ). They must have inhereted the persian infrastructure as well. That way parthian armies could move very efective through their lands.
