Bridge The original staircase descending from the bridge to Kampa Island was replaced by a new one in 1844. The following year, a new flood threatened the integrity of the bridge, but ultimately there were no significant damage . In 1848 , during the days of the Revolution , the bridge escaped unharmed to the guns , although some of the statues were damaged . In 1866 , lights were installed pseudo- Gothic style ( gas initially , but later would be replaced by electric) on the railing of the bridge. In the 1870s the first regular public transport (bus ) became operational on the bridge , which would be replaced later by a tram pulled by horses. It was also in 1870 that the bridge would be called by its current name from Charles Bridge. Between 1874 and 1883 , the towers underwent a thorough renovation . Between 2 and 5 September 1890 , another flood of catastrophic proportions affected and caused significant damage Prague Charles Bridge . Hundred boats , trunks and other floating material from upstream began to form as a barrier against the bridge piled . As a result of the pressure , three of the arches of the bridge were shot down and two of its pillars collapsed due to erosion caused by water. Along with the fifth pillar , two statues built by Ferdinand Brokoff ( those of San Ignacio de Loyola and San Javier) also fell into the river . Recovery efforts demanded two years ( the bridge was reopened on November 19, 1892 ) and cost 665,000 crowns.
