In 1975, the new ferroconcrete bridge was built, and it was named Grinevsky Bridge, after Ignacy Hryniewiecki - the assassin of Tsar Alexander II of Russia, who threw the bomb into tzar's cart near the location of the modern bridge.
Tetsujirō Furukawa donated ferroconcrete school buildings designed by William Merrell Vories for the Toyosato Elementary School in 1937.
