If you've ever struggled through the stuffy underground passages while switching between Metro Lines1, 3 and 4 at Shanghai Railway Station, the upcoming changes will make your journey much easier.

The North Square of the station will undergo a renovation, with over 58 million yuan (US$8 million) being invested to improve passenger flow, according to the official bidding plan announcement.

The project will feature an upgraded transfer hall for Metro Lines 3 and 4.

A new 9,205-square-meter transfer hall will be constructed on the east side of the Metro Line 1 station.

Passengers will be able to transfer between Lines 1, 3, and 4 without exiting the station, eliminating the need for new security checks and reducing transfer time.

Currently, Line 1 operates beneath the South Square, while Lines 3 and 4 serve the North Square, creating a transfer process that typically takes passengers between 5 and 10 minutes. The new transfer hall is expected to address this gap by providing a direct, interconnected pathway within the station complex.

The bidding starts from September 20.
