Despite these inquiries and complaints, the local government continued to collect tolls. The toll collection rights were eventually sold to a public corporation, the Capital Development Corporation, and the time of toll collection was lengthened by 30 years. The central government's general accounting office investigated and found that in the 14 year period (up to 2005), the total toll revenue was over 3 billion yuan; this was much higher than the original investment amount, 1.2 billion yuan. Under pressure, the local government lowered the toll from 15 to 10 yuan. CNY 0.5/km as of 5th Ring Road intersection for sections south of the toll gate.
