It is an important component of the Expressway running through Hefei city. As the original G206 passed though the city along Hefei-Huainan Highway, West Second Ring, South Second Ring and Hefei-Anqing Expressway, the conflict between through and urban transports became increasing serious: the original G206 failed to fulfill its function as an arterial highway and seriously interfered with the urban traffic. The updated G206 has effectively lifted the traffic pressure and played an important role in reasonably diverging transit and urban transports.
