The plan for the extension to Hangzhou was first approved by the central government in February 2006, with a planned date of completion in time for 2010. Work was suspended in 2008, owing to public protests over radiation fears.[4] According to China Daily, as reported on People's Daily Online February 27, 2009, the Shanghai municipal government is considering building the maglev line underground to allay the public's fear of electromagnetic pollution, and the final decision on the maglev line has to be approved by the National Development and Reform commission.

The extension to Hangzhou was finally approved in March 2010, with construction to start in 2010 [5]. The new link will be 199.5 km (124 mi) long, 24 km (15 mi) longer than the original plan. The top speed is expected to be 450 km/h (280 mph) but limited to 200 km/h (120 mph) in built-up areas.
