Within the city of Moscow the Yauza is spanned by 21 road bridges, five railroad bridges, one dedicated tram bridge, two Moscow Metro bridges, numerous pedestrian bridges and the historical Rostokino Aqueduct. Spring floods due to low clearance under old bridges were common, with four in the 1950s alone (1951, 1952, 1955 and 1957); they were practically eliminated when these bridges were rebuilt to modern standards. The most recent flash flood on the Yauza occurred August 14, 2003, following a record-setting rainfall. The Yauza and its valleys are not particularly prone to the landslides and erosion common in the western and southern districts of Moscow. There were two minor landslides on the Yauza in 2008, compared with 40 on the Chertanovka River and 33 on the Gorodnya River.
