The bridge was built in 1954 to a design by Franciszek Szelągowski, carrying National Road 50 over the Vistula between Góra Kalwaria and Ostrówek. In 2017, the Year of the Vistula, efforts led by regional researcher Łukasz Maurycy Stanaszek secured the name Nadwiślańskiego Urzecza: the Karczew council approved it on 28 November and Góra Kalwaria on 29 November. Renovation began in August 2022, with expansion joints, surfacing, anti-corrosion protection, drainage and barriers replaced; completion was planned for February 2023.

The bridge's name, adopted in 2017 during the Year of the Vistula, honours the Urzecze, the ethnographic region of the middle Vistula valley. The initiative came from Łukasz Maurycy Stanaszek, a researcher of that region; the councils of Karczew and Góra Kalwaria passed the naming resolutions on 28 and 29 November 2017.
