THE city government yesterday released its proposals for the development of the subway system over the 2017-25 period. Among the possible projects are lines connecting Chongming Island to the Pudong New Area — via a bridge over the Yangtze River — another linking Shanghai International Tourism and Resorts Zone to the Gaohang area, and a third connecting the Hongqiao Transportation Hub to Shanghai East Railway Station, which is currently under-construction close to the new Disney resort. The proposed program of works will involve 285 kilometers of track across nine lines, it said.
