Tongji Bridge, Stone bridge in Yuyao City, China.

Tongji Bridge is a stone arch bridge in Yuyao that spans the water with three openings. The central opening forms the main passage, while broad steps on top provide pedestrian access across it.

The bridge was first built during the Northern Song dynasty and has undergone several rebuildings since then. A major renewal took place during the Yuan dynasty after a Buddhist monk initiated the reconstruction effort.

The name Tongji comes from a line in the I Ching meaning that boats and oars aid passage where no road exists. A local legend tells that the bridge gave Yuyao good feng shui and produced many officials; when a rival tried to have it demolished, a minister hid it under a cloth so the imperial order could not be carried out.

The bridge carries daily traffic and has 106 steps, with a roadway for carts on both sides of the staircase that narrows from 6.43 meters at the ends to 5.61 meters in the middle. The central arch rises 8.4 meters, allowing boats to pass without lowering their sails. Look for the 24 stone balusters and 22 railing panels.

The bridge is recognized as the first large stone arch construction in eastern Zhejiang and shows early engineering skill in the region. This achievement earned it recognition as an important landmark for local history.
