On April 11, the first-phase traffic diversion was completed at Shixin Road Station of the eastern extension project of Shanghai Rail Transit Line 21, creating favorable conditions for the main structure construction of the station.

Shixin Road Station is located north of the intersection of Chuannanfeng Highway and Shixin Road. During construction, traffic on Chuannanfeng Highway was diverted to both sides, with a one-side temporary road width of 8 meters; the intersection was channelized and the curve section widened to ensure vehicle passage.

To ensure smooth surrounding traffic after the diversion, the Fourth Branch organized municipal and district traffic police and all participating construction units to conduct on-site verification multiple times, and held a mobilization meeting on the division of work for the traffic diversion to plan ahead. Through the concerted efforts of all parties, the diverted road was officially put into use, and the enclosed site was completed in a timely manner, creating favorable conditions for the start of the station's main structure construction.
