The Tokiwabridge (常盤橋) is a bridge over the Nihonbashi River between Ōtemachi, Chiyoda, Tokyo and Nihonbashi Motoishi-chō, Chūō, Tokyo. There are actually two separate "Tokiwa Bridges": a pedestrian-only stone bridge which led to a gate of Edo Castle and a road bridge constructed after the 1923 Great Kanto Earthquake located 70 meters away. Both of these bridges are made from stone, have a double arch structure. | ||||||
