The Shanghai Metro company announced that services will be suspended on half of Line 4, the circular line, over the Spring Festival Break. The work is necessary due to subsidence at Hailun Road Station.
Line 4 will temporarily operate on the segment between Yishan Road and Linping Road only. On most of the missing section, this won’t be too much of a problem as Line 3 services call at all stations between Baoshan Road and Yishan Road. However note that Linping Road is now something of a dead-end (click to enlarge map).
The shutdown will last from January 23 to 28. Normal operations will resume after the holidays.
