Aioi Bridge
The is an unusual "T"-shaped three-way 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 and also because the bridge was close to the center of the city. Although the bridge was not destroyed by the atomic blast, it did sustain heavy damage. After the war, the bridge was repaired and remained in service for nearly four decades, before it was replaced by a new bridge (built as a replica) in 1983. A surviving portion of a floor girder from the original bridge was subsequently donated to the Hiroshima Peace Memorial Museum. The longer part of the bridge crosses the Ōta River just to the north of the island containing the district of . The downstroke of the "T" links the main bridge to the island, and is also the north entrance to the Hiroshima Peace Memorial Park is a memorial park in the center of Hiroshima, Japan.

Three-way Bridge
A multi-way bridge is a bridge with three or more distinct and separate spans, where one end of each span meets at a common point near the centre of the bridge. Unlike other bridges which have two entry-exit points, multi-way bridges have three or more entry-exit points. For this reason, multi-way bridges are not to be confused with commonly found road bridges which carry vehicles in one direction from one entry point, and then bifurcate into two other one-way bridges. Description Multi-way bridges are located throughout the world, though they are rare. Some are as small as a footbridge, while others are multi-lane roadways. Three-way bridges are often referred to as "T-bridges" or "Y-bridges", due to their shape when viewed from above. Three cities in Michigan each have a three-way bridge named "Tridge", combining "tri" and "bridge": The Tridge (Midland, Michigan), The Tridge (Ypsilanti, Michigan) and The Tridge in Brighton, Michigan. The unique shape of a multi-way bridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aiming Point
{{Unreferenced, date=April 2007 In field artillery, the accuracy of indirect fire depends on the use of aiming points. In air force terminology the aiming point (or A.P.) refers to holding the intersection of the cross hairs on a bombsight when fixed at a specific target. An indirect fire aiming point provides a point of angular reference to aim a gun in the required horizontal direction – azimuth. Until the 1980s aiming points were essential for indirect fire artillery. They are also used by mortars and machine guns firing indirectly. An essential requirement of an aiming point is that it be at a sufficient distance from the gun using it. The reason for this is that, while firing, guns, particularly towed guns, move back a short distance – perhaps a foot, as their spades embed and may move more in soft ground. When they Traverse (gunnery), traverse their barrels their sights also move because they are not at the point of pivot. All this means that if the aiming point is too ...
