Surface investments in connection with subway line 4
A major milestone was reached in 2010: the rebuilding and resurfacing of Budapest’s Fővám Square and Kálvin Square was completed. Started in 2007, the project involved the reconstruction of the tracks of trams 47 and 49 between Astoria and Szabadság Bridge, the public utility networks around Fővám Square and Kálvin Square, and also the Kálvin Square underpass, and turned a section of Baross Street into a pedestrian thoroughfare. The following were achieved: a green area on the northern side of Fővám tér consisting of several circular green spots, playground with rubberized asphalt, granite playing tables, benches, granite outdoor steps, basalt tile paving, granite mosaic city walls, three lit fountains emerging from the ground, and one green granite – a sight even when dry – decorative fountains, as well as a 1st World War monument. The finished project is an additional gem among Budapest’s treasures.
