The Tridge is the formal name of a three-way wooden footbridge spanning the confluence of the Chippewa and Tittabawassee Rivers in Chippewassee Park near downtown Midland, Michigan, in the Tri-Cities region. Named as a portmanteau of "tri" and "bridge", the structure opened in 1981. It consists of one 31-foot (9.4 m) tall central pillar supporting three spokes. Each spoke is 180 feet (55 m) long by 8 feet (2.4 m) wide.

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.
