Multi-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.[1]
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 "The Tridge", combining "tri" and "bridge".[1]
The unique shape of a multi-way bridge makes it easy to identify from an airplane. Pilot Amelia Earhart described Zanesville, Ohio as "the most recognizable city in the country" because of its Y-shaped bridge,[2] and the pilots of Enola Gay aimed for Hiroshima's T-shaped Aioi Bridge when they dropped the atom bomb.[3]
