The interchange channels at Shentangqiao Station of Hangzhou Metro Lines 2 and 19 are officially put into use today. This enables citizens along Line 2 in the north of the city to have more convenient access to Hangzhoudong Railway Station, Hangzhouxi Railway Station, Hangzhou Airport, Xixi National Wetland Park, and Future Sci-tech City and will effectively relieve the traffic jam of the city.
