User:Colapeninsula/Hassfurt Bridge

From Wikipedia, the free encyclopedia

The Hassfurt Bridge (or Haßfurt Bridge) is an iron cantilever bridge across the river Main in the town of Haßfurt, Bavaria. Built by Heinrich Gerber in 1867 with a center span of 425 ft (130 m), the Gerber truss road bridge is reckoned the first modern cantilever bridge in the world.[1][2]

Design

[edit]

The bridge uses the form of a Gerber truss, which combines a truss structure with cantilevering. This offers an improvement upon a design with separate trusses.[3]


Influences

[edit]

It influenced the construction of other more famous cantilever bridges, the Forth Bridge in Scotland[1] and later the Niagara Cantilever Bridge and the Quebec Bridge in Canada.[2]
