Starting from 10:00 am on August 10, five interchange ramps of Zhonghe Flyover situated at the center of Hangzhou opened for trial run as the expansion and renovation project of the flyover came to a close. The old flyover will continue to function as the transportation interchange hub of downtown Hangzhou.

Zhonghe Flyover has been the central node of south-north traffic axis in downtown Hangzhou. Five interchange ramps that opened this time were east-to-south on-ramp, north-to-east off-ramp, north-to-west off-ramp, south-to-east off-ramp, and south-to-west off-ramp.
