Moscow Canal
In the 19th century the eastern end of Vodootvodny Canal was closed by a dam with locks, located about 150 meters west (upstream) from the tip of Balchug island. In 1930s, this dam was demolished as part of Moscow Canal project and replaced with a temporary bridge for trams and automobiles. This bridge was torn down upon completion of Bolshoy and Maly Krasnokholmsky Bridges (before World War II).
