In 1751, during the Qianlong Reign of the Qing Dynasty, a wealthy merchant named Huang Mingjue drowned when his ferry capsized in the swollen waters of the Yuxi River. His grieving widow, Mrs. Zhou, resolved to build a stone bridge to prevent future tragedies. Hoping to limit her financial burden, she publicly pledged to fund exactly "one arch," expecting the community to co-fund the rest. The master mason, understanding the poverty of the local villagers, outwitted her. He designed a single, massive arch that spanned the entire river from bank to bank. This design required no central piers, holding Mrs. Zhou to her literal promise and leaving her to pay the entire bill.

Locals quickly named the structure the Widow’s Bridge, though officials registered it as Fuxing Bridge, meaning Good Fortune. For centuries, this green limestone monument served as a crucial transshipment hub along the Hunan-Guangdong Ancient Path, carrying salt and iron down to the Wujiang River.

The bridge is a marvel of longitudinal joint masonry, stretching up to thirty-four meters long and nearly seven meters wide. Visitors climb forty-six stone steps to reach the flat deck—twenty-seven steep steps on the west side leading to Pengjiawan, and twenty-one gentler steps on the east. Standing on the deck, you are suspended more than eight meters above the water. Looking down, the semi-circular arch reflects in the clear river, forming a perfect, shimmering circle.

Time has integrated the bridge into the local ecosystem. Thick-rooted wild chaste trees grow directly out of the exterior arch walls, their woody roots binding the limestone blocks. Below, the riverbed is littered with white granite stones that seem to rise with the water levels during the spring floods—a phenomenon celebrated as "Yuxi Chunzhang," one of the historical eight views of Yizhang.

Today, the bridge remains a living part of the community. On hot summer days, local boys leap from the high stone deck into the deep pools below, while elders walk the same worn stones that Qing Dynasty merchants trod. It stands as a monument to a widow's grief, a builder's cleverness, and the enduring strength of stone.
