Bridges of Piazza di San Marco
At certain times of year, the square may be flooded for several hours at a time by the acqua alta, or "high water," which is caused by a combination of high tide, low barometric pressure, and winds blowing north up the Adriatic Sea. Temporary walkways provide access to the basilica and vaporetto stops at such times, and the city government is planning to raise the square's pavement to minimize such flooding in the future.
