The Danube Bridge (also known as the Friendship Bridge;[1][2] Bulgarian: Мост на дружбата, Most na druzhbata or, more commonly, Дунав мост, Dunav most; Romanian: Podul Prieteniei or Podul de la Giurgiu) is a steel truss bridge over the Danube River connecting the Bulgarian bank to the south with the Romanian bank to the north and the cities of Ruse and Giurgiu respectively.

Opened on 20 June 1954[3] and designed by Soviet engineers V. Andreev and N. Rudomazin,[4] the bridge is 2,223.52 m (7,295.0 ft) long and was, at the time, the only bridge over the Danube shared by Bulgaria and Romania, with other traffic being served by ferries and land routes.

The central part of the bridge (85 m) is mobile and can be lifted for oversized boats passage.

The bridge was constructed in two and a half years with the aid of the Soviet Union.

Both Romania and Bulgaria became a part of the Schengen area on 1 January, 2025, therefore border control is expected to cease operations on 30 June 2025.
