One aspect of this was the new highway, known as the magistrála, which became operational in the 1970s and 80s, cutting through swathes of the city centre including Wenceslas Square – the reason why the National Museum is divorced from the rest of the Square. The magistrála was to continue through the southwest of Prague, and under the plans for the road, it would span the Botič valley. A team of engineers were appointed, including architect Stanislav Hubička, and construction of the Nusle Bridge began in 1967; 17 tenement blocks in Nusle were demolished as part of the construction process. The structure, officially categorized as a box girder bridge, was built from pre-stressed concrete and opened six years later, on 22 February 1973. Somewhat predictably, it was named after a member of the Communist pantheon, Klement Gottwald, Czechoslovakia’s loathed “first working-class president“.
