Trojský tramvajový most, former tram bridge over the Vltava in Holešovice, Prague, Czech Republic

Trojský tramvajový most, nicknamed "Rámusák", was a steel truss bridge over the Vltava that carried the tram line Partyzánská – Trojská – Hercovka – Ke Stírce. Two narrow emergency walkways ran alongside the tracks, but the public was not allowed to use them.

The tram line Nádraží Holešovice – Ke Stírce opened on 5 May 1977 with a steel beam bridge, a temporary substitute during construction of the new Barikádníků bridge. Cracks found in 1980 halted traffic on 10 November; the span was removed and a steel truss bridge, previously a road replacement for Barikádníků, was moved onto the original PIŽMO piers. Its first half opened on 7 March 1981, the second track on 1 July 1982, and the last regular trams crossed on 6 October 2013, followed by museum tram No. 9048 the next day.

Prague tram drivers nicknamed the bridge "Rámusák" ("the noisy one") for the rattle of trams crossing its steel truss. The structure was a reused wartime-era replacement span moved onto the original PIŽMO piers, and its two narrow emergency walkways beside the rails were closed to the public.

The bridge was dismantled from October 2013; by mid-May 2014 the piers were removed to 1.5 metres below the riverbed. The site is now open water, and the new Trojský most stands nearby carrying trams, cars, cyclists and pedestrians.

The bridge's steel sections were not scrapped: Metrostav moved them to its yard in Počernice for refurbishment, as the universal structure can be reused on building sites or after floods. Site manager Tomáš Jurečka noted that, apart from the lowest bolts exposed to water, every bolt came loose.
