The Aioi Bridge (aioi hashi) is an unusual "T"-shaped bridge in Hiroshima, Japan. The original bridge, constructed in 1932, was the aiming point for the 1945 Hiroshima atom bomb because its shape was easily recognized from the air. A replica was constructed in 1983. The longest part of the bridge crosses the Ota River just to the north of the island containing the district of Nakajima-cho. The downstroke of the "T" links the main bridge to the island.
