Starý most, Steel girder bridge in Bratislava, Slovakia

Starý most is a steel truss bridge over the Danube in Bratislava, its gray beams forming a repeating triangular pattern along both sides, with rust-colored sections on the upper chords. A flat deck runs beneath the truss, carried by concrete piers; a small white sign with red text is fixed to the left side of the truss. The bridge now serves pedestrians, cyclists and trams between the Old Town and Petržalka.

The first steel bridge on the site opened in 1890 as Franz Joseph Bridge, part of the Pozsony–Szombathely railway, and was renamed Štefánik Bridge after 1918. Retreating German troops blew up its steel section in 1945; the Red Army and German prisoners of war rebuilt it within about half a year, and it reopened in early 1946 as the Red Army Bridge. Intended to last 15 years, it served until 2 December 2013, when demolition began. A new bridge on the original piers, raised in height, opened for trams, cyclists and pedestrians in December 2015.

The bridge's names track Bratislava's political history: Franz Joseph Bridge after the Austrian emperor who attended its 1890 opening, Štefánikov most in the First Czechoslovak Republic, and Most Červenej armády after 1945. It was renamed Starý most (Old Bridge) in 1990 following the Velvet Revolution.

The rebuilt bridge carries only trams, cyclists and pedestrians; there is no car lane. Trams run on tracks laid in the deck between the truss girders, so cyclists and walkers keep to the side paths. The span rests on the original stone piers, raised in height during the 2014-2016 rebuild.

The steel truss was made in the Vítkovice ironworks, and the bridge carried a single-track railway that led nowhere at either end after 1983. Trams ran across it from 1951 until 1961, when service stopped because of the bridge's worsening condition. The old deck weighed 28 tonnes and was removed during the 2010s works.
