Poniatowski Bridge (Polish: Most Poniatowskiego) - originally built between 1904 and 1914, as Warsaw's third bridge, it was damaged in each of the World Wars and rebuilt afterwards.
It spans the Vistula, connecting Powisle with the Praga quarter on the other side. Its viaduct is an extension of Aleje Jerozolimskie.

The 506 m long steel bridge, consisting of eight spans, was designed by Stefan Szyller. Despite being viewed by many as an extravagance it was opened on January 6, 1914, by the Russian Governor General, Georgi Skalon.
Its official name was "Bridge of Our Most Gracious Ruler, Tsar Nicholas II" (Warsaw then being part of the Russian Empire, following the 18th-century partitions of Poland).
After Poland regained independence in 1918, the bridge was renamed after Prince Jozef Poniatowski and acquired a new nickname - "Poniatoszczak" - which it retains to this day.
